Question

The value of (7+4√3) (7-4√3) is​

Answer 1

(7 + 4√3)(7 - 4√3)

We know that (a+b)(a-b) = a^2 + b^2,

Thus,

(7+4√3)(7-4√3)

= (7)^2 - (4√3)^4

= 49 - 48

= 1.0

Thereby, th correct answer is 1.0

Answer 2

Answer:

(7+4√3) (7-4√3)

Apply (a+b)(a-b) = (a^2-b^2)

[ (7^2) - (4√3)^2]

[ 49 - 48 ]

= 1
