\[= -2 + \sqrt{7}\]
will be the denominator

Answer 3

and doodle tech, I think only the 7 will be under the root.

Answer 4

Yeah only the 7 would be. I messed up on typing the equation.

Answer 5

(5/3)*(-2+sqrt(7)) To get this you must rationalize the denominator. Times both top and bottom by (-2-sqrt(7))
