please simplify this question I cant understand ​

Answer 1

Answer:

$\frac{ \sqrt{5 }+ \sqrt{3} }{ \sqrt{80} + \sqrt{48} - \sqrt{27} - \sqrt{45} } \\ \sqrt{80} = \sqrt{2 \times 2 \times 2 \times 2 \times 5} = 4 \sqrt{5} \\ \sqrt{48} = \sqrt{2 \times 2 \times 2 \times 2 \times 3} = 4 \sqrt{3} \\ \sqrt{27} = \sqrt{3 \times 3 \times 3} = 3 \sqrt{3} \\ \sqrt{ 45} = \sqrt{3 \times 3 \times 5} = 3 \sqrt{5} \\ = \frac{ \sqrt{5} + \sqrt{3} }{4 \sqrt{5} + 4 \sqrt{3} - 3 \sqrt{3} - 3 \sqrt{5} } \\ = \frac{ \sqrt{5} + \sqrt{3} }{4( \sqrt{5} + \sqrt{3} ) - 3( \sqrt{5} + \sqrt{3} ) } \\ = \frac{ \sqrt{5} + \sqrt{3} }{(4 - 3)( \sqrt{5} + \sqrt{3} ) } \\ = \frac{1}{4 - 3} \\ = \frac{1}{1 } = 1$

I have typed it for long time..
