Working out the following additions
√8 + √18

Answer 1

The answer to the following is:
7.07106781187

Answer 2

`\fbox{7.07...}`

First, we need the square of both numbers (8 and 18)

square of 8:

`√(8)`

`=2.828`

square of 18:

`√(18)`

`=4.242`

Now, let's add both numbers:

`2.828+4.242`

`=7.07`
