Question

Compare each pair of radical expressions. Write equivalent or not equivalent for each pair.

Answer 1

Explanation:

1. The first one is equivalent since

`√(48)=√(16\cdot 3)-√(16)\cdot √(3)=4√(3).`

2. It is not equivalent

`√(75)=√(25\cdot 3)=√(25)\cdot √(3)=5√(3)\\eq 7√(5)`

3. It is equivalent

`-√(360)=-√(4\cdot 90)=-√(4)\cdot √(90)=-2√(90).`
