Question

If 3^y = z, then 3^(y+2) =

Please answer clearly and explain the solution clearly and easy to understand. Thanks!
(guaranteed medal for a good answer)

Answer 1

3^(y+2) = 3^y * 3^2
= z * 9

Answer 2

please explain

Answer 3

(a^x ) (a^y) = a^(x+y)

Answer 4

u can write that in reverse 2

Answer 5

sorry i can't understand it that much
please explain more

Answer 6

w8
i think i understand it

Answer 7

\[so \ 3^{y+2} \ can\ be \ written \ as (3^{y})(3^{2}))\]

Answer 8

give another sample question
and i'll answer it

Answer 9

5^x = z , then whts 5^(x+3)

Answer 10

875

Answer 11

howcome?

Answer 12

because 5^(x+3) is also equal to (5^x)(5^3)
then i replaced the 5^x to z
and it will become
z(5^3)
=125z
oooooops. my earlier answer is wrong thought z is 7
