Question

Calculati media geometrica a numerelor a= $(2- \sqrt{3} )^{2} si b= (2+ \sqrt{3} )^{2}$

Answer 1

mg=√a*b= √(2-√3)² * (2+√3)²
mg=|2-√3| * |2+√3)
mg=(2-√3)(2+√3)
mg=4-3
mg=1

Answer 2

$mg= \sqrt{a.b}$

$mg =  \sqrt{(2+ \sqrt{3}) ^{2} (2- \sqrt{3}) ^{2} }$

$mg = |(2- \sqrt{3})| |(2+ \sqrt{3})$|

mg = 4-3 = 1
