1.
How did it break down to ???
square root of 6 (11 square root of 2 minus 2 square root of 2)
I did everything in the paranthesis first
(11 square root of 2 minus 2 square root of 2)
(9 square root of 2)
(which breaks down to 3 square root of 2)
so far I got square root of 6(3 square root of 2)
what do I do next?
