= √36×2+√400×2-√9×2

= 6√2 + 20√2-3√2

= 6+20-3(√2)

= 26- 3(√2)

= 23√2

The answer is 23√2...

Answer 2

$\mathsf \red{Given : } \\ \\ \mathsf{ \sqrt{75} + \sqrt{800} }$

$\mathsf{ = \sqrt{25 \times 3} + \sqrt{400 \times 2} } \\ \\ \mathsf{ = 5 \sqrt{3} + 20 \sqrt{2} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: } \\ \\ \mathsf \red{values \: to \: be \: noted : \: \: \: \: \: \: \: \: \: \: } \\ \\ \mathsf{ \sqrt{3} = 1.732 } \\ \\ \mathsf{ \sqrt{2} = 1.414}$

$\mathsf \red{So }$

$= \mathsf{5 \sqrt{3} + 20 \sqrt{2} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: } \\ \\ \mathsf{ = 5(1.732) + 20(1.414)} \\ \\ \mathsf{ = \: 8.66 \: \: + \: \: 28.25 \: \: \: \: \: \: \: \: \: \: }$

$\mathsf{ = \: 36.94}$
