Multiplying/Dividing Radicals Multiplying/Dividing

Multiplying/Dividing Radicals The rules are simple: multiply/divide everything outside the radicals together and multiply/divide everything inside the radicals together. Ex: 3 8 𝑥 4 𝑦 6 ∙ 2 4 𝑥 3 𝑦 3 6 32 𝑥 7 𝑦 9 24x3y4 2𝑥𝑦 Ex: 3 18 𝑥 2 𝑦 9𝑥 9𝑥 2𝑦 9𝑥 2𝑦

The Exception Try not to end with a radical in your denominator. If you have a radical in your denominator, multiply the entire expression by 1 using the radical as both the numerator and denominator. For example… 3 2 2 75 (multiply expression by 75 75 , which equals 1) 3 2 2 75 ∙ 75 75 = 3 150 150 3 150 150 = 3 25 ∙ 6 150 = 15 6 150 15 6 150 = 6 10
