Question

Calculați media geometrica la: x=8-2•3si y=2la puterea3 rapid va rog frumos dau coroana

Answer 1

$x = 8-2 \cdot 3 = 8-6 = 2 \\ y = 2^{3} = 2 \cdot 2 \cdot 2 = 8 \\ \\ m_g = \sqrt{x \cdot y} = \sqrt{2 \cdot 8} = \sqrt{16} = 4$

Answer 2

m.g. = Radical ( 8 - 2x3) x 2^3 = Radical ( 2 x 2^3)  = Radical 2^4 = 2^2 = 4
