Answer:  3

Step-by-step 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 = [tex]x^{2}[/tex]

[tex]\sqrt{9}[/tex] = [tex]\sqrt{x^{2} }[/tex]  [use square root to cancel the power of 2].

[tex]\sqrt{9}[/tex] = x

x = 3

Check: [tex]3^{2}[/tex] = 3 x 3 = 9
