👉 Learn how to find the square root of rational expressions. To find the square root of a rational expression, we first express the rational expression as the square root of the numerator divided by the square root of the denominator. Next we rationalize the rational expression by multiplying both the numerator and the denominator by the square root of the denominator. Where the rational expression can divide, we divide the numerator by the denominator and then find the square root of the resulting quotient. Where the denominator is a perfect square, we simply find its square root and simplify.
