Va rog mult de tot, dau coroana ​

Answer 1

Răspuns:

Explicație pas cu pas:

1/2 + 1/3 - 1/12 = 6/12 + 4/12 - 1/12 = 9/12 = 3/4

√7 1/9 = √64/9 = 8/3

x = 3/4*8/3 = 2

_________

1/2 - 1/3 + 1/12 = 6/12 - 4/12 + 1/12 = 3/12

√(5^2 - 4^2) = √(25 - 16) = √9 = 3

y = 3/12*3 = 9/12 = 3/4

_________

x*y = 2*3/4 = 3/4

media geometrica = √(3/4) = √3/2
