how do i solve (22/4)^3/2??? without using a calculator
(11/2)^3/2 = 11/2 * sqrt(11/2) = 11/2 * sqrt(11) / sqrt(2)
If you are going to be doing maths without a calculator, I would highly recommend committing to memory or a reference table the square and cube roots of the first ten or more primes. Personally, I prefer the calculator
In this particular case:
sqrt(11) = ~3.31662
sqrt(2) = ~1.41421
11 * sqrt(11) / sqrt(2) = ~25.7973
