Best ResponseYou've already chosen the best response.0The denominator is not supposed to have a square root. So when you rationalize you get rid of the square root in the denominator by multiplying the numerator and denominator by the square root, which is essentially multiplying by 1 so it doesnt change the value of the expression.

Best ResponseYou've already chosen the best response.0LIke for 4/sqrt(7p). Multiply the numerator and denominator by sqrt(7p). So the denominator gets "rationalized" because sqrt(7p)*sqrt(7p) is simply 7p.

Best ResponseYou've already chosen the best response.0so the answer would be : 4 sqr.7p ? or 4sqrt.7p/7p ?
