Choose the correct simplification of .

OpenStudy (anonymous):

\[\frac{ 3^{8} }{ 3^{3} }\]

OpenStudy (anonymous):

since the base is the same you know what?

OpenStudy (anonymous):

@MATTW20

OpenStudy (anonymous):

what?

OpenStudy (anonymous):

the base of each is the same(3)

OpenStudy (anonymous):

just pretend the 3 is an x

OpenStudy (anonymous):

now what's your answer?

OpenStudy (anonymous):

u need to subtract the exponents right? 8 - 3 = 5 so ... x^5 ?

OpenStudy (anonymous):

now just replace the x with 3 and there you go

OpenStudy (anonymous):

3^5 ? or i need to divide the coefficients... 3 / 3 = 1

OpenStudy (anonymous):

no don't do that

OpenStudy (anonymous):

these are my choices: 243 15 1/243 1/15

OpenStudy (anonymous):

hold on a sec

OpenStudy (anonymous):

oky doky....

OpenStudy (anonymous):

those are all your choices?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

in my lesson it says.. divide coefficients and subtract exponents

OpenStudy (raden):

3^5 = 3 * 3 * 3 * 3 * 3 = ...

OpenStudy (anonymous):

o yea 3^5 lol i kept doing 3^3. Thanks @RadEn

OpenStudy (anonymous):

so just do what raden did and you'll get your answer it's there

OpenStudy (anonymous):

243? or 1/243? @RadEn

OpenStudy (anonymous):

you should get 243

OpenStudy (anonymous):

i did... but what about 3^3 ?

OpenStudy (anonymous):

there is no 3^3 that was just me being stupid lol

OpenStudy (anonymous):

i accidentally looked at another problem and came back to this one and started thinking it was 3^3 instead of 3^5

OpenStudy (anonymous):

the equation is \[\frac{ 3^{8} }{ 3^{3} }\]

OpenStudy (anonymous):

and you get 3^5 when you simplify

OpenStudy (anonymous):

3^5=243

OpenStudy (anonymous):

ohhhh

OpenStudy (anonymous):

\[\frac{ 3*3*3*3*3*3*3*3 }{ 3*3 }\rightarrow \frac{ 3*3*3*3*3*3 }{ 1 }\rightarrow 729\]
