1.) C - The solution is also -12 because negatives multiplied by negatives cancel each other out.
2.) D - What you did was you chose the answer that looked like where C is. Notice how there is a square root symbol next to the numbers.
4.) C - The square root is 8.3666002534... It would round to 8 and 9.
7.) A - 5 to the third power is 125. (5 x 5 x 5 = 125)
