Question

A. 18
B. 0
C. -1
D. 1

Answer 1

You don't speak Math? That's fine :) I shall translate for you :)
\[\huge \log_bM\]just means the exponent you need to raise b to so that you get m.

So...
\[\huge \log_{18}18\]
just means "the exponent you need to raise 18 to... to get 18.
So to what exponent do you raise 18 to get 18?
