Question

Calculati media geometrica a numerelor a=(3-22)² si b=(3+2√2)². AJUTORR.

Answer 1

a=(3-2√2)²
b=(3+2√2)²
a*b= (3-2√2)² *(3+2√2)²= ((3-2√2(3-2√2) )²= (9-8)²=1²=1

m.g (a,b) =√ab=√1=1



daca textul e cum ai scris tu, atunci
a=(3=-22)²=(-19)²=19²
si
b=(3+2√2)²

ab =19² *(3+2√2)²

m.g (a,b) =√(19² *(3+2√2)²)=19(3+2√2)
