Kurahisisha maneno na watazamaji
Kurahisisha maneno kwa kutumia Mali ya Bidhaa kwa Watazamaji
Kurahisisha maneno kwa kutumia Mali ya Nguvu kwa Watazamaji
Kurahisisha maneno kwa kutumia Bidhaa kwa Mali ya Nguvu
Kurahisisha maneno kwa kutumia mali kadhaa
Kuzidisha monomials

Kumbuka

Kabla ya kuanza, fanya jaribio hili la utayari.

kurahisisha: $\frac{3}{4}\cdot \frac{3}{4}$
Kama amekosa tatizo hili, mapitio Zoezi 1.6.13.
Kurahisisha: $(−2)(−2)(−2)$ .
Ikiwa umekosa tatizo hili, tathmini Zoezi 1.5.13.

Kurahisisha Maneno na Watazamaji

Kumbuka kwamba exponent inaonyesha kuzidisha mara kwa mara ya kiasi sawa. Kwa mfano, $2^4$ ina maana ya bidhaa ya $4$ mambo ya $2$ , hivyo $2^4$ ina maana $2·2·2·2$ .

Hebu tuchunguze msamiati wa maneno na watazamaji.

NUKUU YA KIELELEZO

$Takwimu hii ina nguzo mbili. Katika safu ya kushoto ni kwa nguvu m. m ni lebo katika bluu kama exponent. a ni kinachoitwa katika nyekundu kama msingi. Katika safu ya haki ni maandishi “kwa m nguvu ina maana kuzidisha m sababu za a.” Chini ya hii ni kwa m nguvu sawa mara mara a, ikifuatiwa na ellipsis, na “m sababu” iliyoandikwa hapa chini katika bluu.$

Hii inasoma $a$ kwa $m^{th}$ nguvu.

Katika kujieleza $a^{m}$ , exponent $m$ inatuambia mara ngapi sisi kutumia msingi a kama sababu.

$Takwimu hii ina nguzo mbili. Safu ya kushoto ina cubed 4. Chini ya hii ni mara 4 mara 4, na “mambo 3" yaliyoandikwa hapa chini katika bluu. Safu ya haki ina hasi 9 hadi nguvu ya tano. Chini ya hii ni hasi mara 9 hasi mara 9 hasi mara 9 hasi mara 9 hasi 9, na “sababu 5" zilizoandikwa hapa chini katika bluu.$

Kabla ya kuanza kufanya kazi na maneno variable zenye exponents, hebu kurahisisha maneno machache kuwashirikisha idadi tu.

Mfano $\PageIndex{1}$

Kurahisisha Maneno Kutumia Mali ya Bidhaa kwa Watazamaji

Umeona kwamba unapochanganya maneno kama hayo kwa kuongeza na kutoa, unahitaji kuwa na msingi sawa na kielelezo sawa. Lakini wakati wewe kuzidisha na kugawanya, exponents inaweza kuwa tofauti, na wakati mwingine besi inaweza kuwa tofauti, pia.

Tutaweza hupata mali ya exponents kwa kuangalia kwa mwelekeo katika mifano kadhaa.

Kwanza, tutaangalia mfano unaoongoza kwenye Mali ya Bidhaa.

	$x mara za mraba x cubed.$
Hii ina maana gani? Ni mambo ngapi kabisa?	$x mara x, kuzidisha kwa mara x x. x mara x ina sababu mbili. x mara x mara x ina mambo matatu. 2 pamoja 3 ni sababu tano.$
Hivyo, tuna	$x kwa nguvu ya tano.$
Kumbuka kwamba 5 ni jumla ya exponents, 2 na 3.	$x mara za mraba x cubed ni x kwa nguvu ya 2 pamoja na 3, au x kwa nguvu ya tano.$

Tunaandika:

$\begin{array}{c}{x^{2} \cdot x^{3}} \\ {x^{2+3}} \\ {x^{5}}\end{array}$

Msingi ulikaa sawa na sisi aliongeza exponents. Hii inasababisha Bidhaa Mali kwa Exponents.

BIDHAA MALI KWA EXPONENTS

Kama $a$ ni idadi halisi, $m$ na $n$ ni kuhesabu idadi, basi

$a^{m} \cdot a^{n}=a^{m+n}$

Ili kuzidisha na besi kama, ongeza vielelezo.

Mfano na namba husaidia kuthibitisha mali hii.

$\begin{array}{rll} {2^3\cdot2^2} &\stackrel{?}{=} & 2^{2+3}\\ {4\cdot 8} &\stackrel{?}{=} & 2^{5} \\ {32} &=& 32\checkmark\end{array}$

Kurahisisha Maneno Kutumia Mali ya Nguvu kwa Wasanii

Sasa hebu tuangalie usemi wa kielelezo ambao una nguvu iliyoinuliwa kwa nguvu. Angalia kama unaweza kugundua mali ya jumla.

	$x mraba, katika mabano, cubed.$
Hii ina maana gani? Ni mambo ngapi kabisa?	$x squared cubed ni x mara squared x mara x squared, ambayo ni x mara x, kuongezeka kwa x mara x, kuongezeka kwa x mara x. x mara x ina sababu mbili. Mbili pamoja na mbili pamoja na mbili ni sababu sita.$
Hivyo tuna	$x kwa nguvu ya sita.$
Kumbuka kwamba 6 ni bidhaa ya exponents, 2 na 3.	$x squared cubed ni x kwa nguvu ya mara 2 3, au x kwa nguvu ya sita.$

Tunaandika:

$\begin{array}{c}{\left(x^{2}\right)^{3}} \\ {x^{2 \cdot 3}} \\ {x^{6}}\end{array}$

Sisi kuzidisha exponents. Hii inasababisha Power Mali kwa Exponents.

NGUVU MALI KWA EXPONENTS

Ikiwa $a$ ni idadi halisi, $m$ na $n$ ni namba nzima, basi

$\left(a^{m}\right)^{n}=a^{m \cdot n}$

Ili kuongeza nguvu kwa nguvu, kuzidisha wafuasi.

Mfano na namba husaidia kuthibitisha mali hii.

$\begin{array} {lll} \left(3^{2}\right)^{3} &\stackrel{?}{=}&3^{2 \cdot 3} \\(9)^{3} &\stackrel{?}{=} & 3^{6} \\ 729 &=&729\checkmark \end{array}$

Kurahisisha Maneno Kutumia Bidhaa kwa Mali ya Nguvu

Sasa tutaangalia maneno yaliyo na bidhaa inayofufuliwa kwa nguvu. Je, unaweza kupata ruwaza hii?

$\begin{array}{ll}{\text { What does this mean? }} & {\text { (2x) }^{3}} \\ {\text { We group the like factors together. }} & {2 x \cdot 2 x \cdot 2 x} \\ {\text { How many factors of } 2 \text { and of } x ?} & {2 \cdot 2 \cdot x^{3}} \\ {\text { Notice that each factor was raised to the power and }(2 x)^{3} \text { is } 2^{3} \cdot x^{3}}\end{array}$

$\begin{array}{ll}\text{We write:} & {(2 x)^{3}} \\ & {2^{3} \cdot x^{3}}\end{array}$

Mtazamo hutumika kwa kila sababu! Hii inasababisha Bidhaa kwa Power Mali kwa Exponents.

BIDHAA KWA MALI NGUVU KWA EXPONENTS

Kama $a$ na $b$ ni idadi halisi na $m$ ni idadi nzima, basi

$(a b)^{m}=a^{m} b^{m}$

Ili kuongeza bidhaa kwa nguvu, ongeza kila sababu kwa nguvu hiyo.

Mfano na namba husaidia kuthibitisha mali hii:

\ [kuanza {safu} {lll} (2\ cdot 3) ^ {2} &\ stackrel {?} {=} &2 ^ {2}\ cdot 3^ {2}\ 6 ^ {2} &\ stackrel {?} {=} &4\ cdot 9\\ 36 &=&36

Kurahisisha Maneno kwa kutumia Mali kadhaa

Sisi sasa kuwa na mali tatu kwa ajili ya kuzidisha maneno na exponents. Hebu muhtasari yao na kisha tutaweza kufanya baadhi ya mifano kwamba matumizi ya zaidi ya moja ya mali.

MALI YA WAPIGANAJI

Ikiwa $a$ na $b$ ni namba halisi, $m$ na $n$ ni namba nzima, basi

$\begin{array}{llll} \textbf{Product Property } & a^{m} \cdot a^{n}&=&a^{m+n} \\ \textbf {Power Property } &\left(a^{m}\right)^{n}&=&a^{m n} \\ \textbf {Product to a Power } &(a b)^{m}&=&a^{m} b^{m} \end{array}$

Mali zote exponent kushikilia kweli kwa idadi yoyote halisi $m$ na $n$ . Hivi sasa, sisi tu kutumia idadi nzima exponents.
