Question

(√3+1) (√3-1) (2-√3) (4+2√3)

Answer 1

Answer:

(√3+1) (√3-1) (2-√3) (4+2√3)= 4

Answer 2

Answer:

4

Step-by-step explanation:

(√3+1) (√3-1) (2-√3) (2×2 + 2×√3)

=> [(√3+1) (√3-1)] × 2[(2-√3) (2+√3)]

By using identity (a+b)(a-b) = a^2 - b^2

=> [(√3)^2 - (1)^2] × 2[(2^2) - (√3)^2]

=> (3 - 1) × 2(4 - 3)

=> 2 × 2

=> 4
