Simplify this expression by using the properites of exponents: (4a)^2 (4a)^5

OpenStudy (anonymous):

\[a ^{x }timesa ^{y}=a ^{x +y}\]

OpenStudy (anonymous):

i got 16a^7 but thats wrong

OpenStudy (anonymous):

the 4a stays as it is, you just add the exponents like you did. Giving you 4a^7. is that what's in the back of the book?

OpenStudy (anonymous):

its online but no it says thats wrong too

OpenStudy (jlastino):

16a^7

OpenStudy (anonymous):

its telling me thats wrong also

OpenStudy (anonymous):

hmm wait. i think i know this lol

OpenStudy (jlastino):

4a^7

OpenStudy (jlastino):

Oh it's only exponents xD

OpenStudy (anonymous):

\[(4a)^2 (4a)^5=(4a)^{2+5}=(4a)^7\]

OpenStudy (anonymous):

lol

OpenStudy (anonymous):

(4a)^7 is not correct either

OpenStudy (anonymous):

maybe they want you to write \(4^7a^7\)

OpenStudy (anonymous):

yep that worked thanks!

OpenStudy (anonymous):

lol

OpenStudy (jlastino):

@satelite73 the question is confusing xD thanks for pointing that out
