You must give the square separately to both sides.
[Note:sqr means square]
Do same to the 2nd one. cube(3/5)=cube(3)/cube(5)=27/125
Now in the 3rd one....
it is sqr(2 1/2)
multiply denominator with the integer . Here you have to do is to multiply the both 2 and then add 1 in it so, (2*2)+1=5
and then put the same denominator with the number you've got, here the answer is..
DO the same in the others and ask me if necessary. ^_^
