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.
