Question

if x= 2/7 √10 what is the value of √1+x -√1-x/ √1+x - √1-x =?​

Answer 1

Answer:

0

Step-by-step explanation:

$\frac{ \sqrt{1} + \frac{2}{7} \sqrt{10} - \sqrt{1} - \frac{2}{7} \sqrt{10} }{ \sqrt{1} + \frac{2}{7} \sqrt{10} - \sqrt{1} - \frac{2}{7} \sqrt{10} } = 0$

Answer 2

Answer:

The answer is :

√1+2/7√10-√1-2/7√10/√1+2/7√10-√1-2/7√10

2/7√11-2/7√9/2/7√11-2/7√9

2/7√2/2/7√2=1
