Question

The value of ( 1/2+ under root 3) + ( 2/ under root 5 - under root 3) + (1/2- underroot 5)​

Answer 1

Answer:

3√3 - 2√15 + 3 - 2√5 all is divided by 2

Answer 2

Answer:

$1 - \frac{3}{ \sqrt{5} }$

Step by step explanation:

$( \frac{1}{2} + \sqrt{3} ) + ( \frac{2}{ \sqrt{5} } - \sqrt{3}) + ( \frac{1}{2} - \sqrt{5} ) \\ = \frac{1}{2} + \sqrt{3} + \frac{2}{ \sqrt{5} } - \sqrt{3} + \frac{1}{2} - \sqrt{5} \\ = \frac{1}{2} + \frac{1}{2} + \sqrt{3} - \sqrt{3} + \frac{2}{ \sqrt{5} } - \sqrt{5} \\ = 1 + \frac{2}{ \sqrt{5} } - \sqrt{5} \\ = \frac{ \sqrt{5} + 2 - ( \sqrt{5})( \sqrt{5}) }{ \sqrt{5} } \\ = \frac{ \sqrt{5} + 2 - 5 }{ \sqrt{5} } \\ = \frac{ \sqrt{5} - 3 }{ \sqrt{5} } \\ = \frac{ \sqrt{5} }{ \sqrt{5} } - \frac{3}{ \sqrt{5} } \\ = 1 - \frac{3}{ \sqrt{5} }$
