Thread: Fractions with a fractional indice

Last thread for a while I hope (lol!).

I apologise for the formatting in advance...

Evaluate (1/4)^5/2



I've just done (1/2)^-2 and I got (2/1)^2 which is fine, but the fractional indice has thrown me off track.

well, yeah, but what is that? that can be greatly simplified

0.25^5 = 0.000976562
Square root of 0.000976562 is 0.031249992
S0 would 0.031 be an appropriate answer?

no.

Oh right I see!
Just a quick question...

How does the squareroot of (1/4)^5 equal the same as (1/2)^5 ?

Thank you.
