Question

3^2x=27

Answer 1

27=3^3
--> 3^2z=3^3
--> 2x=3
--> x=3/2

Answer 2

i meant 2x in the second step.

Answer 3

since 27 = 3^3, you can write it like this

\[\huge 3^{2x}=3^3\]
Now since the bases are equal, you can just set the exponents equal to each other.

Answer 4

umm. is it 3^(2x) or (3^2)*x ?
i told you what you have to do if its the former..
if its the latter then..
9*x=27
--> x=3..
