Question 268178
I can only guess the actual expression is:
{{{log(7, (7^5))}}}
because
{{{log(7, (75))}}} is NOT equal to any of the answers provided.<br>
If you understand what logarithms are, then this problem is fairly simple. Logarithms are exponents. {{{log(a, (b))}}} represents the exponent which, if placed on a base of a, results in b. Your expression, {{{log(7, (7^5))}}} represents the exponent on 7 that results in {{{7^5}}}. Well, it's pretty obvious that the exponent on 7 that results in {{{7^5}}} is 5!
