Recognize that the notation means “the log base number raised to the power is… that will help you to set up the solution to a problem in any base.

Explanation:

Recognize that the notation means “the log base number raised to the power is… that will help you to set up the solution to a problem in any base.

log_(base) x = exponent on the base number.

In this case, it is “The number that results from raising 2 (the base) to the 5th power.
2^5 = x
x = 32

ANOTHER example would be:
log_4x = 3 In this case, the base is 4 and the exponent is 3.
4^3 = x
x = 64
