Solve for x and check. Enter only a number. 3^2x=27 HINT: Express 27 as a power of 3.

OpenStudy (anonymous):

to me i think the answer i think its 3 @ganeshie8

ganeshie8 (ganeshie8):

\(3^{2x} = 27\)

ganeshie8 (ganeshie8):

\(3^{2x} = 3^3\)

ganeshie8 (ganeshie8):

since base is equal, exponents are also equal : \(2x = 3\) \(x = 3/2\)
