The operation that gives the exponent to which base b must be raised to obtain x is called what?

Explanation:
The operation is a logarithm. It finds the exponent you must raise base b to reach x. In symbols, if b^k = x, then k = log_b(x). This makes it the inverse of exponentiation. For example, since 3^4 = 81, the logarithm log_3(81) equals 4. Remember: the base is the number you multiply by itself, the exponent is the power you raise it to, and a radical is a root—unrelated to finding that exponent.
