In each case, you can start by taking the antilog.

21. x = 4^(3/2)
  x = 8

22. 81 = x^(4/3)
  81^(3/4) = x = 27

24. 2x - 3 = 6^0
  2x = 4 . . . . . add 3
  x = 2

25. 5 - x = 16^(1/2)
  5 - 4 = x = 1

Length of a rectangular prism volume is 2,830.5, width 18.5, height 9
jek_recluse [69]
Well, you get the volume by multiplying the height, the width, and the length. So just work on it backwards.
2,830.5 divided by (9 times 18.5).
9 times 18.5 is 166.5. So that leaves us with 2,830.5 divided by 166.5, which is 17.
So, the answer is 17.
