Answer 1

3/√48 - √75 × √48 + √75/ √48 + √75

= 3(√48 + √75) / (√48)² - (√75)²

= 3(6.928 + 8.660) / 48 - 75

= 3(15.588) / - 27

= 15.588 / - 9

= - 1.732 ANS

Answer 2

Hey mate ,

$\frac{3}{ 4\sqrt{3} - 5 \sqrt{3} }$

$\frac{3}{ - \sqrt{3} }$

$- \frac{3}{ \sqrt{3 } } \times \frac{ \sqrt{3} }{ \sqrt{3} }$

$- \frac{3 \times \sqrt{3} }{ \sqrt{3 \times \sqrt{3} } }$

$\frac{ - 3 \sqrt{3} }{3}$

$- \sqrt{3}$

$- 1.732$

Hope you find it helpful !!!
