Question

calculati media aritmetica a numerelor :  
a)2 la puterea 56 si 2 la puterea 59 .................... b) 2 si 2 la puterea 7 
 Va rog ajutatima

Answer 1

$M _{aritmetica} = \frac{ 2^{56} +2 ^{59} }{2} = \frac{2^{56}(1+2 ^{3}) }{2} =9* 2^{55} = 3^{2}*2^{55}$

$M _{aritmetica} = \frac{ 2+2 ^{7} }{2} = \frac{2(1+2 ^{6}) }{2} =1+2 ^{6} =1+64=65$
