Q. Use an exponent to condense the expression below. Then compute.\newline−2×−2×−2×−2 -2 \times-2 \times-2 \times-2 \newlineType the base, then use the ab a^{b} button or use the ∧ { }^{\wedge} symbol on your keyboard for the exponent.\newlineCondensed form:\newlineAnswer:
  1. Identify base and repetition: Identify the base and the number of times it is being multiplied by itself.\newlineThe base is −2-2 and it is being multiplied by itself 44 times.\newlineCondensed form: (−2)4(-2)^4
  2. Compute (−2)4(-2)^4: Compute the value of (−2)4(-2)^4.
    (−2)4(-2)^4 means −2-2 multiplied by itself 44 times.
    (−2)×(−2)×(−2)×(−2)=16(-2)\times(-2)\times(-2)\times(-2) = 16, because a negative number multiplied by a negative number is a positive number, and 2×2×2×2=162\times2\times2\times2 = 16.
    Answer: 1616
