The first thing you need to do, is put the like terms in order. So it would be, (-3x)-2x+7x-15xy+4xy.(basically the 4xy and 2x switch places, just take the sign that's in front of them with them.) Now you would combine the like terms. ((-3x)-2x+7x)-(15xy+4xy). Simplified, the new equation is 2x-19xy.

Shtirlitz [24]

When trying to find a root of a number ( the little number included with the square root symbol) this is the same as raising the number to that fraction.

Example : ∛5 would be the same as 5^1/3

So in the given problem the 5th root can be written as x^1/5

Now the number is 13^3, so to simplify the 5th root, the value could be written as 13^3/5
