Question

What is the missing base of 9=____ to the power of 2?

Answer 1

Answer: 3

Explanation:

Let x be the missing base. In this case, base to the power of 2 means this number x times itself will equal 9.

9 =
`x^(2)`

`√(9)` =
`\sqrt{x^(2) }` [use square root to cancel the power of 2].

`√(9)` = x

x = 3

Check:
`3^(2)` = 3 x 3 = 9
