Explanation

26% of 450 is 117. 117 + 3^2 = 117 + 9 = 126. (?)^3 + 1 = 126, so (?)^3 = 125. Therefore, ? = 5.

AI explanation

Approximate the equation to 26 percent of 450 plus 3 squared equals the cube of the question mark plus 1. Calculate 26 percent of 450 to get 117, and add 9 to get a sum of 126. Subtracting 1 from 126 leaves 125, and since the cube root of 125 is 5, the result is 5.
