What approximate value should come in the place of the question mark (?) in the following equation? 347.88 = 28.9 × 15.98 + 143.96 = (?)^3 + 210.91

1. 5
2. 7
3. 9
4. 11

Correct answer: 5

Solution

The equation is an approximation-based simplification. Estimating the arithmetic gives a value close to 336 for the part involving the cube, and subtracting 210.91 leaves about 125, whose cube root is 5.
