Question 698161: How do I simplify an expression where you add whole numbers under the square root symbol? The problem would read in words: the square root of 20 plus 20 plus 20 NOT the square root of 20 plus the square root of 20, etc.
Thank you Answer by solver91311(24713) (Show Source):
Then, since the prime factorization of 60 is we can write:
Note that a pair of factors inside the radical becomes a single factor outside the radical.
By the way, in plain text, is written sqrt(X). Your problem here could have been written sqrt(20 + 20 + 20). Note that the parentheses are ALWAYS necessary to define the radicand.
