    9 = 3^2 9^2x = 3^4x 27 = 3^3 Compare 4x = 3 x = 3/4

    We have\[9^{2x}=27\] \[(3^{2})^{2x}=3^{3}\] \[3^{4x} = 3^{3}\] so 4x = 3

    9 is nothing but 3^2 and 27 is 3^3 so we need to make the base common to make it possible to solve for 'x'.... so............... 3^2(2x) = 3^3 therefore 3^4x = 3^3 since the base is the same, the exponents are equal;( since it is an equation and the left hand side is equal to the right hand side). so, 4x = 3 hence x = 3/4

    If you need to do it with logarithms, then take logarithms of both sides of 9^2x = 27
