Question 64489
Solve for x:
1) {{{log4(1) = x}}} The base is 4. Rewrite this in exponential form.
{{{4^x = 1}}} Now take the log (base 10) of both sides.
{{{xlog(4) = log((1))}}} Divide both sides by log(4).
{{{x = (log(1))/log(4)}}} But log(1) = 0:
{{{x = 0}}}

2) {{{log3(x) = 5}}} The base is 3. Rewrite in exponential form.
{{{3^5 = x}}}
{{{x = 243}}}
