Solve: (100)^1.5

Correct answer: 1000. (100)^1.5 = 100¹ × 100^½ = 100 × 10 = 1000.

Background: 1.5 = 1 + 1/2, and the power 1/2 means square root.

• 100: 100 is only 100¹.
• 5000: 5000 is not 100 × 10.
• 10000: 10000 is 100².

Did you know? (100)^1.5 can also be written as 10³.

Memory trick: 100 × √100 = 1000.
