Question

Express in simplest radical form.
V40

Answer 1

`\huge\boxed{2 √(10)}`

Explanation:

When taking a square root and making it a radical, we need to list out it's factors and find which one we can take the square root of.

The factors of 40 are:

1, 2, 4, 5, 8, 10, 20, 40.

Out of these, we need to look for one that we can find the square root of.

We know that the square root of 4 is 2.

Therefore, we can make
`√(40)` into
`√(4 \cdot 10)`.

The square root of 4 is 2. Therefore, we can put that outside the radical.

`2 √(10)`.

Hope this helped!
