I asked a question and it was answered by Steve. He had the numbers wrong. The problem should be sqrt of 18 over (sqrt of 8)-3. not sqrt of 18 -3. I got 2+sqrt of 8. Is it correct?

I looked at how Steve answered your question and he did it correctly.

(Trust Steve's answers !!)

The way you just typed it now, it would be

√18/√18 - 3
which would simply be 1 - 3 or -2
