Question

(2√8−3√2)whole square
solve the problem with concept.​

Answer 1

Step-by-step explanation:

$(2 \sqrt{8} - 3 \sqrt{2} ) {}^{2}$

$= (2 \sqrt{8} ) {}^{2} + (3 \sqrt{2}) {}^{2} - 2 \times 2 \sqrt{8} \times 3 \sqrt{2} \\ = 4 \times 8 + 9 \times 2 - 12 \sqrt{16} \\ = 32 + 18 - 12 \times 4 \\ = 50 - 48 \\ = 2 \: ans$

Answer 2

Answer:

2

Step-by-step explanation:

$2\sqrt{8} = 2 \sqrt{4 \times 2 \: } = 4 \sqrt{2}$

Hence,

$(4 \sqrt{2} \: - 3 \sqrt{2})^{2} = ( \sqrt{2} )^{2} \\ = 2$
