Can anyone help :S?

5√2187x^8 y^29

p.s the 5 is supposed to be the 5th root to the numbers inside.

Surely you have some idea what to do. I've done the difficult part for you, now finish it.

Re: Can anybody help me with this math question? No idea what to do.

Hi math121,

Maybe this might help you

5th root of x^8=(x^8)^1/5=(x^5*x^3)^1/5=x*x^3/5= x* 5th root ofx^3
