Pleaseee!!!!! Nimeni nu ma ajutaa



DOAR subpuncetele:b, C, d​

Answer 1

Răspuns:

a) $\frac{2}{2 \sqrt{3} } + \frac{5}{5 \sqrt{3} } - ( \frac{3 \sqrt{3} }{8} + \frac{1}{ \sqrt{3} } ) \\ \frac{ \sqrt{3} }{3} + \frac{ \sqrt{3} }{3 } - \frac{17 \sqrt{3} }{24} \\ \frac{2 \sqrt{3} }{3 } - \frac{17 \sqrt{3} }{24} \\ \frac{16 \sqrt{3} - 17 \sqrt{3} }{24} = - \frac{ \sqrt{3} }{24}$

b)2√6+6/4+23/√2+2√3/√2

2√6+6/4+√6+√6=

17√6/4
