Math theory question - x^1/2 and rt(x) [ difference between x to the power half and square root of x ]

Guardian's picture

Something a lot of people have asked me and a lot of them get wrong the first time, so I thought this deserves a thread of its own

A) Is there a difference between 4^(1/2) and rt(4), if yes what?, if no why not?


The other questions on similar lines

B) What are the possible values of :
1] rt(4)
2] rt([-2]^2]
3] 4^1/2
4] [(-2)^2]^1/2
