Question

Express in simplest radical form.

Square root of 160

Answer 1

`4√(10)`

Explanation:

160 = 16 * 10

`√(160) = √(16 \cdot 10) = √(16) \cdot √(10) = 4√(10)`

we cannot simplify further as 10 is 2*5, there are no more squares to simplify.

Answer 2

4
`√(10)`

Explanation:

Simplify

`√(160)`

We can rewrite this as

`√(16 * 10)`

Breaking this up

`√(16) √(10)`

We know the square root of 16 is 4

4
`√(10)`

sqrt(10) cannot be simplified so
