The first two are correct to the nearest integer.

The third is a trick question, you cannot take the square root of a negative number
Katie
oh thanks
Reiny
let's look again at the third

if you had √-47 there would be no answer
but if you had
- √47 then it would be -6 to the nearest integer.

Actually, I think -7 is closer to -√47 than is -6.

-√47 = -6.85
