Long division
** **

I am really struggling with long division all together. Not just one specific step. But I particularly get lost after the first step. I think I am trying to do too much.
@&
First, you have to be sure you are adept at long division with numbers. I recommend some practice with this so the procedure is very clear to you.
Then you can check out Internet resources. Searching under 'Long Division of Polynomials' I quickly found a number of links, including the following:
https://www.khanacademy.org/math/algebra2/polynomial_and_rational/dividing_polynomials/v/polynomial-division
Note that we also have tutors in the Tutor Center who can provide excellent help with this.
Naturally I'll also go over an example in class

When completing radicals, what do you do if y or x is raised by a number. For example one of the questions was y raised to the 10. What was I suppose to do?

I'm not sure what expression the expression y^10 might have been part of, but suppose you had the cube root of y^10.
That could be expressed as
(y^10) ^(1/3),
which by the laws of exponents is
y^(10/3).
Since 10/3 = 3 1/3, this could be written as
y^(3 + 1/3) = y^3 * y^(1/3)
so that the cube root of y^10 can be written as
y^3 * cube root of y.
