I can only guess the actual expression is:
log%287%2C+%287%5E5%29%29
because
log%287%2C+%2875%29%29 is NOT equal to any of the answers provided.

If you understand what logarithms are, then this problem is fairly simple. Logarithms are exponents. log%28a%2C+%28b%29%29 represents the exponent which, if placed on a base of a, results in b. Your expression, log%287%2C+%287%5E5%29%29 represents the exponent on 7 that results in 7%5E5. Well, it's pretty obvious that the exponent on 7 that results in 7%5E5 is 5!
