Solve log base 2 of x equals 5. What is x?

Explanation:
Logarithms turn a number into the exponent that produces it. If log base 2 of x equals 5, that means 2 raised to the 5th power equals x. So x = 2^5 = 32. You can verify by checking that log base 2 of 32 is indeed 5. The other numbers correspond to different exponents (16 = 2^4, 8 = 2^3, 64 = 2^6), not 5.
