Question

root 2 over root 2 plus root 3 minus root 5​

Answer 1

Answer:

√2 / √2 + √3 - √5 = undefined

Step-by-step explanation:

= √2 (√2 + √3 + √5)

(√2 + √3 - √5) ( √2 + √3 + √5)

Using identity, (a + b) (a - b) = a^2 - b^2

= √2^2 + √3 + √5

   (√2 + √3)^2 - (√5)^2

=  2  + √3 + √5

    (2 + 3) - (5)

= 2 + √3 + √5

        (5) - (5)

= 2 + √3 + √5
