Find the 4th term in the expansion of (2x - y)6.
Explain the thought process leading to the answer
When rationalizing a denominator, should I multiply it by just the number that is square-rooted or the whole number?
Example: 5/2{Square root sign}3: should it multiplied by the square root of 3 over the square root of three or should it be multiplied by the 2 times the square root of three over two times the square root of three?
