Question 947737
{{{7^(4x) = 45}}}


{{{log(7^(4x)) = log(45)}}}


{{{(4x)log(7) = log(3^2*5)}}}


{{{(4x) = (log(3^2)+log(5))/log(7)}}}


{{{x = (2log(3)+log(5))/4log(7)}}}


{{{x = (2*0.4771212547+0.69897)/(4*0.84509804)}}}


{{{x = (0.9542425094+0.69897)/(3.38039216)}}}


{{{x = 1.6532125094/3.38039216}}}


{{{x = 0.4890593845774391}}}


{{{x = 0.4891}}}
