Question

simplify (8 +√ 3) (8 – √3)

Answer 1

Answer:

61

Step-by-step explanation:

let, 8=a & √3= b

using identity => (a+b)(a-b) = a²-b²

we get => 8²-(√3)² = 64-3 = 61

Answer 2

Step-by-step explanation:

we know that (a+b) (a-b) =a square - b square

so,(8+√3)(8-√3) = 8 square-√3square

= 64-3

= 61 (answer)
