I need help with this I have no clue on what to do??
I have to simplify the expression
its number 31 on this site http://cphs.dadeschools.net/departments/mathematics/alg2/Source/la207bad.pdf it says 125^2/9 * 125^2/9 over 5^1/4

note the following four facts:
125 = 5^(something)
(a^b)^c=a^(b*c)
a^b * a^c = a^(b+c)
a^b / a^c = a^(b-c)
