Evaluate to the nearest tenth.

Question

6 sqrt 10 subtract 9

sqrt 80 divided by sqrt 8

So, for #1, I got 10. Is it correct?
And #2, I got 3.2 Is it correct?

Thanks in advance for the replys,

Answer 1

The first answer is correct to the nearest tenth.

For #2, sqrt80/sqrt8 = sqrt10 = 3.16..., so 3.2 is also correct to the nerest tenth.
