Which of the following is a value of x that satisfies logx 36 = 2 ?

  1. 4
  2. 6
  3. 8
  4. 16
  5. 18

Answer

The correct answer is B.

By definition, logx 36 is the power of x that it would take to be 36. That power is 2 from the right side of the equation.

So, x2 = 36.

This equation is satisfied when x = 6.
