Advanced Math practice question

If 2^(x − 2) = 16, what is the value of x?

Answer: 6

16 = 2⁴, so x − 2 = 4 and x = 6.

Common wrong answers

If you answered 2
2 subtracts instead of adding the shift.
If you answered 4
4 is x − 2, not x.
If you answered 18
18 adds 2 to 16 as if the exponent were the value.
