1st one: We would do (87)^3 because we're multiplying (87) 3 times. Either way we would get the same answer.
2nd one: x = 30. To get the answer follow the steps:
Step 1: First, we have to multiply both sides by 5.
x/5 = 6
(x/5) * (5) = (6) * (5)
3rd one: to find the area, we have to multiply w * l, so 17 * 80, which equals 1,360.
4th one: 125829 rounded to the nearest hundredth is 12.58
I hope this helps! :>
