Which of the following expressions is equivalent to (4s) ?
A. B. C. 2 D.
Explanation: DTaking a number to the power is the same as taking the cube root of the number. Therefore, (4s) = . The correct answer is (D). A shortcut is to just raise the coefficient to the power, and then use POE. Since only one answer starts with , that one must be correct. Another approach is to plug in a number for s and let the calculator do the hard work, though that would not help in this section since calculator use is not permitted.
