[tex]({ \frac{1}{ \sqrt{11} } + \frac{1}{ \sqrt{11} } })^{^{2} } [/tex]
​

Answer 1

Penjelasan dengan langkah-langkah:[tex]({ \frac{1}{ \sqrt{11} } + \frac{1}{ \sqrt{11} } })^{^{2} }[/tex][tex] = ( \frac{ \sqrt{11} }{11} + \frac{1}{ \sqrt{11} } ) {}^{2} [/tex][tex] = ( \frac{ \sqrt{11} + \sqrt{11} }{11} ) {}^{2} [/tex][tex] = ( \frac{2 \sqrt{11} }{11} ) {}^{2} [/tex][tex] = \frac{(2 \sqrt{11}) {}^{2} }{11 {}^{2} } [/tex][tex] = \frac{4( \sqrt{11} ){}^{2} }{11} [/tex][tex] = \frac{4 \times 11}{11 {}^{2} } [/tex][tex] = \frac{4}{11} [/tex]
