The exponent that would follow (3 • 4) to make the equation true is 2.
Note that (3 • 4) is equal to 12. Therefore, we can rewrite the equation as:
(3^2)(4^2) = 12^2
Simplifying the right-hand side:
(3^2)(4^2) = 144
Comparing this to the left-hand side, we see that the exponents of 3 and 4 are both 2.
Therefore, the exponent that would follow (3 • 4) to make the equation true is 2.
