√ Simplifying Radicals <<Only perfect squares can be taken out of radicals>> √1 1 √4 2 √9 3 √16 4 √25 5 √36 6 √49 7 √64 8 they When radicals include variables, are still √81simplified the same9way 1)√100 Factor the radicand into 10its factors and expand the √121 11 variable(s). √144 12 2) Bring any variable listed twice in the radicand to the outside. * X = Steps to simplify: 1. Divide the number under the radical by the largest perfect square that can go into it. 2. Simplify the perfect square, and keep the multiplier Examples: under the radical. √75 The biggest perfect square that can be divided into 75 is 25 √75= √25x5 Examples: √x4 = √x*x*x*x X If there is not a perfect square under a radical, you can SIMPLIFY it! X2 √Y3Z6 = √y*y*y*x*x*x*x*x*x √25 becomes 5, the √5 remains under the radical Final Answer: 5√3
