Question

Calculati media aritmetica a nr. 2 la puterea 17 ; 2 la puterea 18 si 3 ori 2 la puterea 19

Answer 1

2 la puterea 17=131072
2 la puterea 18=262144
3*524288=1572864

Answer 2

2¹⁷+2¹⁸+3x2¹⁹ = 2¹⁷(1+2+3x2²) = 2¹⁷(3+3x4) = 2¹⁷(3+12) = 2¹⁷x15
ma = (2¹⁷x15):3 (se simplifica 3 cu 15)
ma = 2¹⁷x5
