Advanced Math practice question

Answer: 9

81 = 3⁴ gives x = 4, and 32 = 2⁵ gives y = 5. So x + y = 9.

Common wrong answers

If you answered 1

1 is 5 − 4.

If you answered 20

20 is 4 × 5, the product of the exponents.

If you answered 113

113 is 81 + 32, adding the values instead of the exponents.
