Question

If root 2=1.414, root 3 =1.732, Find the value of Root 2+1/Root 2-1​

Answer 1

Answer:

root2 + 1/ root2 - 1

Multiply top and bottom with root 2 + 1

so the bottom part will cancel due to identity==> (a+b)(a-b) = a^2 - b^2

so you will be left with (root2 + 1)^2 on the top

Expand that

==> 2 + 1 + 2root2 ==> 3+ 2(1.414)

= 3+2.828 = 5.828

Answer 2

Answer:

9.893

Step-by-step explanation:

Root 2+1/ Root 2-1 => (1.414+1.732)/(1.414-1.732)

=> 3.146/(-0.318)

=> 9.893
