poo, on my Mac, the √ symbol did not show up, I got a ã ,

but I know what you meant ....

what computer do you have ?

√18/√8 - √2

= 3√2/2√2 - √2

= 3/2 - √2

we could form a common denominator of 2 to get

(3-2√2)/2

sqrt 18/sqrt 8 - sqrt 2

3 sqrt 2 / 2 sqrt 2 - sqrt 2

= (3/2) - sqrt 2

I bet you left out a parenthesis

try

sqrt 18/(sqrt 8 - sqrt 2)

3 sqrt 2/(2 sqrt 2 - sqrt 2)

3 sqrt 2/sqrt 2

3
