Understanding properties of radicals will help you quickly solve this problem. Dividing Radical Expressions A common way of dividing the radical expression is to have the denominator that contain no radicals. Tackle divisions of two numbers with fractional exponents by subtracting the exponent you’re dividing (the divisor) by the one you’re dividing (the dividend).
