Solve the exponential equation. 9^(2x) = 27

OpenStudy (anonymous):

Hey... simplify it as powers of 3 on both sides. Compare the powers on both sides to get the answer.

OpenStudy (anonymous):

how do you compare the powers?

OpenStudy (dumbcow):

what they mean is if bases are same then you can equate the exponents \[b^{m} = b^{n} \rightarrow m = n\]

OpenStudy (anonymous):

but isnt there only one expo?

OpenStudy (anonymous):

Here we can compare powers just because the bases are 3 on both sides...

OpenStudy (anonymous):

Oh so 3^2x=9?

OpenStudy (dumbcow):

well 9 and 27 are both powers of 3 ............. 3^2 and 3^3

OpenStudy (anonymous):

Ohhh
