Question

Simplify 2 root 8 minus 3 root 2 power 2

Answer 1

Step-by-step explanation:

$2 \sqrt{8} - ( {3 \sqrt{2} })^{2} \\ 2 \sqrt{8} - (3 \times 3 \times \sqrt{2 \times \sqrt{2} } ) \\ 2 \sqrt{8} - (9 \times 2) \\ (2 \sqrt{2 .2.2} )- (9 \times 2) \\ (2 \times 2) \sqrt{2} - (9 \times 2) \\ 4 \sqrt{2} - (9 \times 2) \\ .....(factor \: 2 \: is \: common. \: so \: we \: devide \: both \: by \: 2) \\ \frac{4 \sqrt{2} }{2} - \frac{(9 \times 2)}{2} \\ = 2 \sqrt{2} - 9$
