If you mean sqrt (3w +13) = sqrt(5w-7) with all terms under the radical, then just square both sides.
then; 3w+13 = 5w-7 ( subtract 3w from each side )
13 = 2w-7 ( add 7 to both sides )
20 = 2w
10 = w
This question cannot be answered. You will have to give me the number to the square root. * * * * * a = ±sqrt(c^2 - b^2)

Yes.
Plus or minus the base. If the base is X and you square it, you get X2. If you take the square root of that, you get Plus or Minus X. This is because X*X equals X2 and -X*-X also equals X2.

x = the square root of -1, an imaginary number written as a lower case italic i.
It cannot be solved because the discriminant of the quadratic equation is less than zero
