Answer 2

Hey there!

8/√3+√5

Rationalising the denominator,

= 8(√3-√5) / √3+√5(√3-√5)

= 8√3-8√5 / √3²-√5²

= 8√3-8√5/-2

= 8(1.732)-8(2.236)/-2

= 13.856-17.888/-2

= -4.032 / -2

= 2.016.

OR YOU CAN DIRECTLY SUBSUTUTE THE VALUES AND FIND THE ANSWER.

8/√3+√5

= 8/1.732+2.236

= 8/3.968

= 2.016.
