X=(2^20)^3 : 2^56-2^3 si Y=(3^23-3^22-3^21-3^20) :3√20+3^0+3
Calculati media geometrica a numerelor X si Y. URGENT!

Answer 1

Răspuns:

Explicație pas cu pas:

X=(2^20)^3 : 2^56-2^3 = 2^60 : 2^56 - 8 = 2^4 - 8 = 16 - 8 = 8

Y=(3^23-3^22-3^21-3^20) :3^20+3^0+3

= 3^3 - 3^2 - 3 - 1 + 1 + 3 = 27 - 9 = 18

X*Y = 8*18 = 144

Mg = √144 = 12
