Question

X = 3√2 · (√50+ √72-√200 )
Y = (1/3√3+1/2√3) · √300: 1 /3√36
a )Arata că X = 6
b) Calculează media geometrică × si y​

Answer 1

Răspuns:

b) 5√3

Explicație pas cu pas:

X = 3√2 · (√50+ √72-√200 )=3√2 ·(5√2+6√2-10√2)=3√2·√2=3·2=6

Y = (1/3√3+1/2√3) · √300: 1 /3√36=(2/6√3+3/6√3)·10√3:1/3·6=5/6√3·10√3:1/3·6=50/2:1/3·6=25·3·6=450

b)√X·Y=√6·450=√2700=30√3
