Question

How do you simplify `sqrt(49)`?

Answer 1

`sqrt49=7`

Explanation:

As `7*7=49` it follows that 7 is the square root of 49.
Therefore `sqrt49=7`

Since we don't have `+-` in front of the square root sign, we are only asked for the positive value.

Answer 2

`sqrt49=7`

Explanation:

`sqrt49`

The radical symbol over a number means to take the square root of that number, or to find the number that can be multiplied by itself to get the number under the radical.

In this case it is `7`, since `7 xx 7 = 49`

The negative root is not asked for in this case.
