Rationalising the sqrts
Please help me rationalise and simplify:
$\frac{1}{\sqrt[3]{2} - 1} - \frac{2}{\sqrt{3} - 2} .$
I have tried using the cube of the denominator and the square of the denominator on the second one but it stuffs up when I try to simplify.
Thanks.

Show that
$\frac{- 4 z^{- 1}}{(1 - \frac{1}{4} z^{- 1}) (1 - 4 z^{- 1})} = \frac{16}{15} \frac{1}{(1 - \frac{1}{4} z^{- 1})} - \frac{16}{15} \frac{1}{(1 - 4 z^{- 1})}$

Simplifying algebraic fractions.
I cannot simplify the following expression. Please need help.
$\frac{3}{x + 1} - \frac{1}{x + 3} + \frac{3}{1 - x} - \frac{1}{3 - x}$
Thanks in advance. Regards !

Simplify with fractional exponents and negative exponents
I am trying to simplify
${(\frac{3 x^{\frac{3}{2}} y^{3}}{x^{2} y^{- \frac{1}{2}}})}^{- 2}$
It seems pretty simple at first. I know that a negative exponent means you flip a fraction. So I flip it.
${(\frac{x^{2} y^{- \frac{1}{2}}}{3 x^{\frac{3}{2}} y^{3}})}^{2}$
Now I need to square it, which is tricky because there are a lot of weird rules with squaring. This is probably where I went wrong.
$(\frac{x^{2} y^{- \frac{1}{2}}}{9 x^{\frac{3}{2}} y^{3}})$
Now I need to try and simplify things. I know that I can get rid of the x on top since there is a larger one on the bottom.
$\frac{4}{2} - \frac{3}{2} = \frac{1}{2}$
$(\frac{x^{\frac{1}{2}} y^{- \frac{1}{2}}}{9 y^{3}})$
Now I need to get rid of the y exponent.
I am not sure how that is possible.

Simplifying a Multi-Variate Fraction
I am an eighth grader in need of a little assistence. I was given a multi-variate fraction, and was told to simplfy it to lowest terms. On of my fellow classmates that is ahead of me in math, tried to explain it to me, but he didn't make sense. We ended up with an answer (shown below), but I wasn't sure how we got it. I want to know this because I feel that it might be important when I embark on Geometry next week. Any ideas?
This is the problem:
Write as a single fraction.
$- \frac{3 b - 5 y}{2 b} + \frac{3 b + 6 y}{8 b} + 2$
Simplify your answer as much as possible
And this is what we got...
$\frac{7 b + 26 y}{8 b}$

If you are dealing with fraction math problems, you are in the correct section as you will find both questions and answers with detailed explanations. Before you study fraction problems with answers, ensure that you explore the original instruction because fraction algebra equations must be understood from a logical point of view. It is what makes fraction problems and answers important as they tend to inspire learners for thinking. If you cannot find a solution for your question, explore more fraction math problems with answers and try to find the rationality of divisions first!
