Question

a=|rad5-2rad2|
b=rad8+rad5
media geometrica=?​

Answer 1

a=|√5-2√2|=-√5+2√2

b=√8+√5=2√2+√5

mg=√a*√b=√(-√5+2√2*2√2+√5)

    =√(-√25+4√4)=√(-5+4*2)=√(-5+8)=√3

Answer 2

Răspuns:  Mg = √3

Explicație pas cu pas:

✻ Salutare! ✻

a = |√5 - 2√2|

a = -√5 + 2√2

b = √8 + √5

b = 2√2 + √5

Mg = √a · √b

Mg =√(-√5 + 2√2)·(2√2 + √5)

Mg = √(-√25 + 4√4)

Mg = √(-5 + 4 · 2)

Mg = √(-5 + 8)

Mg = √3
