Question

How do you simplify `sqrt(21/4)`?

Answer 1

`sqrt(21)/2`

Explanation:

`sqrt(21/4)` is equivalent to `sqrt(21)/sqrt(4)`. `sqrt(21)` cannot simplify since it has no factors that can be square rooted and it cannot be square rooted itself.

However, we know that `sqrt(4) = 2`.

So the final answer is `sqrt(21)/2`.

Hope this helps!
