Question

Which of the following is equivalent to 2^4 =16?
Select one:
A. log4^16 = 2
B. log2^4 = 16
C. log2^16 = 4
D. log4^2 = 16

Answer 1

If you have a^x = b, you can rearrange the equation into a logarithm so that:

loga b = x

This reads "log base a of b equals x".

You should be able to substitute a, x, and b with values from your original question to get the right answer.
