Question

Solve the following quadratic equation.

(x - 16)2 = 256

A. x = 30 and x = 8

B. x = -30 and x = -8

C. x = -32 and x = 0

D. x = 32 and x = 0

Answer 1

Answer:

log b x = y. with b being the base, x being a real number, and y being an exponent. For example, 2 3 = 8 ⇒ log 2 8 = 3 (the logarithm of 8 to base 2 is equal to 3, because 2 3 = 8). Similarly, log 2 64 = 6, because 2 6 = 64. Therefore, it is obvious that logarithm operation is an inverse one to exponentiation.
