Question

(3+√2)(2+√2)
give a proper solution ​

Answer 1

Answer:

$(3 + \sqrt{2} )(2 + \sqrt{2} ) = \\ \\ = > (6 + 3 \sqrt{2} + 2 \sqrt{2} + \sqrt{2} \times \sqrt{2} ) \\ \\ \\ = > (6 + 4 \sqrt{2} + 2) \\ \\ = > (8 + 4 \sqrt{2} ) \\ \\ \\ = > 4(2 + \sqrt{2} ) \\ \\ = > 4(2 + 1.41) \\ \\ = > 4(3.41) \\ \\ = > 13.64$

Answer 2

$\Large\underline\mathbb\blue{ANSWER}$

$\: \: \: {(3 + \sqrt{2})(2 + \sqrt{2}) }$

$\implies6 + 6 \sqrt{2} + 2 \sqrt{2} + 2 \\ \implies 8 + 8 \sqrt{2} \\ \implies \: \boxed{ \pink{8(1 + \sqrt{2} )}}$

8(1+1.41) = 8 × 2.41 = 19.28
