Question

Between what 2 integers does √89 fall?

Answer 1

The square root of 89 falls between the integers 9 and 10. The answer is actually 9.4339. You can check this answer by multiplying 9x9 to get 81. Once you know this, you can see that you have to add more to the original formula to get it to come up to 89.

Answer 2

 $9^{2} = 81$ and $10^{2} =100$ which means that $\sqrt{81} =9$ and $\sqrt{100} =10$

since 89 is in between 81 an 100,  $\sqrt{89}$ is in between 9 and 10.

The correct answer is A.
