Answer 1

4

Answer 2

how did you get tht

Answer 3

yes, its factored as a difference of squares so you get a^2 which is 3 squared (9) minus root of five squared which is five so 9-5=4

Answer 4

\[(3+\sqrt{5})(3-\sqrt{5})\]square the 3s and the root 5
9-5=4

Answer 5

(3-V5)*(3+V5)
it is in the form of (a-b)(a+b) = (a^2-b^2)
