Question

rationalise the denominator number of √3+√11/2√5-√11​

Answer 1

Step-by-step explanation:

Given expression1+2−31

= 1+(2−3)1 × 1−(2−3)1−(2−3)

= 1−(2−3)21−(2−3)

= 1−(2+3−26)1−(2−3)

= −4+261−(2−3)

Answer 2

$\frac{ \sqrt{3} + \sqrt{11} }{2 \sqrt{5} - \sqrt{11} } \times \frac{2 \sqrt{5} + \sqrt{11} }{2 \sqrt{5} + \sqrt{11} } \\ \\ = > \frac{2 \sqrt{15} + \sqrt{33} + 2 \sqrt{55} + 11}{20 - 11} = \frac{2 \sqrt{15} + \sqrt{33} + 2 \sqrt{55} + 11 }{9}$
