Question 383530
Solve for x, to the nearest thousandth.
{{{8^(2x-1) = 90}}} Is this right? Take the log of both sides.
{{{Log(8^(2x)) = Log(90)}}} Apply the power rule to the left side.
{{{2x*Log(8) = Log(90)}}} Divide both sides by {{{Log(8)}}}
{{{2x = Log(90)/Log(8)}}} Evaluate the right side.
{{{2x = 1.0269}}} Divide both sides by 2.
{{{x = 0.513}}}
