-5+4 7(square root)

------------------------

12

-------------------------

36 + 5 7(square root)

--------------------------

36

Flipping the bottom would get me:

-5 + 4 7 (squared) (36 - 5 7 (squared))

----------------------- ------------------------

36 + 5 7 (square) (36 - 5 7 (squared))

I'm not sure if this is correct or not, from looking at my notes the denominator

is suppose to be a number.

-180 + 25 7 (squared) + 144 7 (squared) - 20 7 (squared)

----------------------------------------------------------------------

1296 - 180 7 (squared) + 180 7 (squared) - 25 7 (squared)
