2*3>2-8/6-4?
8/7 to the power of -3 is 0.669921875
(1/2)3 = 13/23 = 1/8
2 power 12 is 8192 and 3 power 8 is 6561
2 to the power of 3 equals 8...2 times 2 is 4 and 4 times 2 is 8.
3 - 8 is already simplified.
8 to the power (2/3) equals 4.
2 and a half - 3 over 8 = 2 1/8
3/8 - 1/2 = 3/8 - 4/8 = -1/8
43/8 - 23/8 = 2/1 or 2
8^(2/3) 8^(1/3) = 2, 2^2 = 4 -> 8^(2/3) = 4
