Question 690295
{{{x=8log(100, (10))}}}
This problem is fairly easy if you really understand what logarithms are. In general logarithms are exponents. Specifically, {{{log(100, (10))}}} is the exponent that one can put on a 100 to get a result of 10. So what power of 100 equals 10? Once you realize that 10 is the square root of 100 and that and exponent of 1/2 means square root, then you will know that {{{log(100, (10)) = 1/2}}}. Now we just substitute this into the equation:
{{{x = 8*(1/2)}}}
which simplifies to:
{{{x = 4}}}
