Q5 Simplify the radical expression. 3\5 + 6/180
To simplify the radical expression 3√5 + 6√180, we need to simplify each radical term first.
√5 is already simplified because there are no perfect square factors of 5.
√180 can be simplified by finding the perfect square factors of 180.
180 = 36 * 5
√180 = √(36 * 5) = √36 * √5 = 6√5
Now, the expression becomes:
3√5 + 6√5 = 9√5
Therefore, the simplified radical expression is 9√5.
