Question

find the value of root 2+root 3 by 2-root 3 if root 3=1.73

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

$\frac{ \sqrt{2} + \sqrt{3} }{ \sqrt{2} - \sqrt{3} } \\ = \frac{( \sqrt{2} + \sqrt{3}) {}^{2} }{( \sqrt{2} + \sqrt{3} )( \sqrt{2} - \sqrt{3} ) } \\ = \frac{2 + 3 + 2 \sqrt{6} }{2 - 3} \\ = \frac{5 + 2 \sqrt{6} }{ - 1} \\ = - 5 - 2 \sqrt{2} \times \sqrt{3} \\ = - 5 - 2 \times 1.414 \times 1.73 \\ = - 5 - 4.892 \\ = - 9.892$
