Question

Choose one operation with radical expressions to discuss in
detail (simplify, add, subtract, multiply or divide). Discuss the steps to
complete the operation and provide a worked out example.

Answer 1

simplify √18

step 1: we need to find the largest perfect square that divides into 18. 9

Step 2: write 18 as the product of 2 and 9. 18=2•9

step 3: use product rule. √18=√9•2= √9•√2= 3√2
