root 5 is

Answer 1

Answer:

√3 + √5 is conjugate of √3 - √5

Step-by-step explanation:

Lets understand first what is conjugate of a surd

Conjugate Surds: Given a surd (√a-√b), its conjugate is defined as (√a+√b) and vice-versa. Means sign of one root is changes

as we know that (a+b)(a-b) = a² - b² so

When a surd is multiplied by its conjugate, their product is no more a surd

(√3 - √5)(√3 + √5)

= 3  - 5

= - 2

√3 + √5 is conjugate of √3 - √5
