Answer 1

Răspuns:

Explicație pas cu pas:

a = 5√2 + 3√5

b =  5√2 - 3√5

mg(a,b) = √(a·b)

mg(a,b) = √[(5√2 + 3√5)·(5√2 - 3√5)] =

= √(50-45) = √5

Answer 2

$M_G=\sqrt{a\cdot b}=\sqrt{(5\sqrt2+3\sqrt5)\cdot (5\sqrt2-3\sqrt5) } = \\ =\sqrt{(5\sqrt2)^2-(3\sqrt5)^2}=\sqrt{(\sqrt{50})^2-(\sqrt{45})^2}= \\ =\sqrt{50-45}=\boxed{\bold{\sqrt5}}$
