Question

Q. (6) Simplify the following expressions:
() (4 + v7)(3+v2)
(ii) (V5-V3​

Answer 1

Answer:

Step-by-step explanation:

Given : (i) (4 + √7) (3 + √2)

= 3(4 + √7) +√2 (4 + √7)

= 12 + 3√7 + 4√2 + √14

(iii) Given : (√5 - 2) (√3 - √5)

⇒   √3(√5 - 2) -√5(√5 - 2)

⇒ √5 × √3 - 2√3 - √5 × √5 + 2√5

⇒ √15 - 2√3 - 5 + 2√5
