Question 108808
Solve for x:
{{{5+ln(x^2) = 4}}} First, subtract 5 from both sides.
{{{ln(x^2) = -1}}} Now apply the power rule to the logarithm. {{{log(x^n) = nlog(x)}}}
{{{2*ln(x) = -1}}} Divide both sides by 2.
{{{ln(x) = -(1/2)}}} Now rewrite the logarithm in exponential form: If {{{Log[b](x) = y}}}, then {{{y^b = x}}}
{{{e^(-1/2) = x}}} Simplify:
{{{x = 1/sqrt(e)}}}
