Question

Calculati media aritmetica a numerelor 2 la puterea 17 , 2 la puterea 18 si 3•2 la puterea 19
Daca se poate si poza va roogg

Answer 1

Ma = (2^17  +  2^18  + 3*2^19) : 3 = 2^17  (1+2+3*2^2) : 3 =

2^17 (3+12) : 3 = 15 * 2^17  :  3 = 5 * 2^17.

Answer 2

( 2¹⁷ + 2¹⁸ + 3 x 2¹⁹ ) : 3 = 2¹⁷ x 5 → media aritmetica a celor trei numere

= 2¹⁷ x ( 1 + 2 + 3 x 2² ) : 3 =

= 2¹⁷ x ( 3 + 12 ) : 3 =

= 2¹⁷ x 15 : 3 =

= 2¹⁷ x 5
