Question

The square root of Eve's age is two more than the square root of Jamil's age. If Jamil is 9 years old, how old is Eve?

Answer 1

Jamil is 9 years old.
The square root of Jamil's age is √9=3.
Eve's age is x.
The square root of Eve's age is two more than the square root of Jamil's age.

$\sqrt{x}=3+2 \\ \sqrt{x}=5 \\ (\sqrt{x})^2=5^2 \\ x=25$

Eve is 25 years old.
