Let's work this by breaking down the different terms and see where we end up.
We start with:
I'll work through the cube roots in the numerator and the roots in the denominator:
First thing I'll do is break down the numbers within the roots to find the cube/square inside the root sign, which will allow us to simplify them. I'm also going to distribute the square root across the
The numerator is now ready for a subtraction and have a single term up top. I can regroup the denominator to perform multiplication.
I'm also going to evaluate the
And here's what we were waiting for (it actually set itself up last step but I wanted to clean things up first before dealing with the cancellation here)
