Question

(4√2+3)(4√2+3) plz tell with formula

Answer 1

Hello Mate!

$(a + b)(a + b) = {(a + b)}^{2} \\ (4 \sqrt{2} + 3)(4 \sqrt{2} + 3) \\ = {(4 \sqrt{2} + 3) }^{2} \\ {(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab \\ {(4 \sqrt{2} )}^{2} + {3}^{2} + 2 \times 4 \sqrt{2} \times 3 \\ (16 \times 2) + 9 + 24 \sqrt{2} \\ 32 + 9 + 24 \sqrt{2} \\ 41 + 24 \sqrt{2}$

Hope it helps☺!

Answer 2

Heya!!!

Here's your answer friend,

(4√2 + 3)(4√2 + 3) = (4√2 + 3)²

....( by using the identity (a + b)(a + b) = (a + b)²)

==> ( 4√2 + 3 )²

==> 32 + 9 + 24√2 ........
........{by using the identity [ (a + b)² = a² + b² + 2ab ] }


==> 41 + 24√2 is the required answer.

Hope it helps you : )
