Question

Media aritmetica a nr :2 la puterea 17,2 la puterea 18 si 3 ori 2 la putera 19 . Offffff ajutati-ma!!!!

Answer 1

$m_a=\frac{2^{17}+2^{18}+3*2^{19}}{3} \\\\ m_a= \frac{2^{17}(1+2+3*2^2)}{3} \\\\ m_a=\frac{2^{17}(3+3*4)}{3} \\\\ m_a=\frac{2^{17}(3+12)}{3} \\\\ m_a=\frac{2^{17}*15}{3} \\\\ \boxed{m_a=2^{17}*5}$
