Question

Fie numerele a=2- radical3 si b=2+ radical3 .Calculati diferenta dintre media lor aritmetica si media lor geometrica

Answer 1

1) ma = ( a + b) / 2 = ( 2 - √3 + 2 + √3) / 2 = 4 / 2 = 2
   ma = 2
2) mg = √ab = √( 2 - √3)( 2 + √3) = √2² - (√3)² = √4 - 3 = √1 = 1
   mg = 1
3) diferenta
   ma - mg = 2 - 1 = 1
