Question 1104266: Rationalize the denominator and simplify if possible
63/ Square root 7
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
rationalize the denominator means to take it out of the square root sign.
start with 63 / sqrt(7)
multiply both numerator and denominator by sqrt(7) and you will get 63 * sqrt(7) / 7
the denominator has now been rationalized.
since 63 / 7 = 9, then the expression can be simplified to 9 * sqrt(7).
you can confirm by evaluating the original expression of 63 / sqrt(7) and seeing that the value is that same as 9 * sqrt(7).
it is.
