Question

What two whole numbers does √89 fall in between ?

Answer 1

Answer:

9 and 10

Step-by-step explanation:

To work this out, you can either evaluate $\sqrt{89}$ or find the 2 closest perfect squares to 89.

With the second method, the 2 closest perfect squares are 81 and 100, otherwise known as 9² and 10². This means $\sqrt{81}$ is between 9 and 10.

With the first method, the result is 9.4339811320... which is between 9 and 10.
