Advanced Math practice question

Answer: 5

2b³ = 250 gives b³ = 125, so b = 5.

Common wrong answers

If you answered 10

10 comes from b³ = 1000, a slip; 250/2 = 125 = 5³, so b = 5.

If you answered 125

125 is b³, not b.

If you answered 41.7

41.7 is 250/6, treating the exponent as a multiplier.
