Question

evaluate (√5+√3)/(√5-√3)+(√5+√3)/(√5-√3)​

Answer 1

Answer:

4

Step-by-step explanation:

We know that (a+b)(a-b) = a^2 - b^2

Hence,

(√5+√3)/(√5-√3)+(√5+√3)/(√5-√3)

                  = ($\sqrt{5}^{2} - \sqrt{3}^{2}$) + ($\sqrt{5}^{2} - \sqrt{3} ^{2}$)

                  = (5-3) + (5-3)

                  = 2+2 = 4
