Question

Find the odd one out: 8, 27, 64, 100, 125.

• A. 27
• B. 64
• C. 100
• D. 125

Hint:

Four of these are perfect cubes.

Answer 1

The Correct Option is C

List cube roots: $\sqrt[3]{8}=2$, $\sqrt[3]{27}=3$, $\sqrt[3]{64}=4$, $\sqrt[3]{125}=5$, but $\sqrt[3]{100}$ is not a whole number. Hence 100 is the exception.
