Answer 1

Step-by-step explanation:

HI mate!!!

It's 4/root 5 + root 3

(4/root 5 + root 3) * (root 5 - root 3 / root 5 - root 3)

4 * ( root 5 - root 3) / (root 5)^2 - (root 3)^2

As (a+b)(a-b) = a^2 - b^2

4* ( root 5 - root 3) / 5 - 3

4 ( root 5 - root 3) / 2

2 ( root 5 - root 3)

Substitute the values

2 (2.236 - 1.732)

1.008
