Q. Use multiplication to expand the expression below. Then compute.\newline(−2)4 (-2)^{4} \newlinePress the × \times button or type the * symbol on your keyboard to represent multiplication.\newlineExpanded form:\newlineAnswer:
  1. Expand (−2)4(-2)^{4}: We gotta expand (−2)4(-2)^{4}, which means (−2)(-2) multiplied by itself 44 times.\newlineSo, (−2)×(−2)×(−2)×(−2)(-2) \times (-2) \times (-2) \times (-2).
  2. Multiply first two: Now let's multiply the first two (−2)(-2)s together.(−2)×(−2)=4(-2) \times (-2) = 4, cuz a negative times a negative is a positive.
  3. Multiply by third: Next, multiply the result by the third −2 -2 . \(4 \times −2 -2 = −8-8 \), again negative times positive is negative.
  4. Multiply by last: Finally, multiply −8-8 by the last −2-2.\newline−8×(−2)=16-8 \times (-2) = 16, negative times negative is positive, right?
