volume_mute
Select all expressions where you must evaluate an exponent before doing any multiplication or division.
Correct Answer
(1) \(-4(-3)^2 - (-2)\)
(2) \(-2^2 - (-2)^2\)
Explanation
\(-4(-3)^2 - (-2)\): contains \((-3)^2\) → evaluate exponent first. \(-2^2 - (-2)^2\): contains two exponential expressions → evaluate both first. The other two have no exponents.
