Thus, what are the rules for simplifying radicals?
The Product Raised to a Power Rule and the Quotient Raised to a Power Rule can be used to simplify radical expressions as long as the roots of the radicals are the same. The Product Rule states that the product of two or more numbers raised to a power is equal to the product of each number raised to the same power.
Can you divide a radical by a whole number?
Answer and Explanation: A radical cannot be divided by a whole number unless the radical is not simplified.
Just as with "regular" numbers, square roots can be added together. But you might not be able to simplify the addition all the way down to one number. ... In order to be able to combine radical terms together, those terms have to have the same radical part.
The short answer is: There are multiple ways of writing the same number, but if we all follow the simplification rules, we'll all write our answers the same way, which makes it easier for people to work together, if they're all expressing their work in the same way.
