1/√2+√3 + 1/√3+√4 + 1/√4+√5 + 1/√5+√6 plis!!! tolong djwb dan cara yg tepat,,,,,

[tex]( \frac{1}{ \sqrt{2} } + \frac{ \sqrt{3} } {1} + \frac{1}{ \sqrt{3} } + \frac {\sqrt{4}}{1} + \frac{ 1 }{ \sqrt{4} }+\frac{ \sqrt{5} } {1} +\frac{1}{ \sqrt{5} } +\frac {\sqrt{6}}{1})^{2} [/tex]
=[tex] \frac{1}{2}+ \frac{3}{1}+ \frac{1}{3}+ \frac{4}{1}+ \frac{1}{4}+ \frac{5}{1}+ \frac{1}{5}+ \frac{6}{1} [/tex]
=[tex] \frac{30+180+20+240+15+300+12+360}{60} = 19.283[/tex]
