Question

Ex 2. Vă rog frumos. Dau si coroborat!! Am nevoie numai de cât!

Answer 1

x/(√2-1)=y/(√2+1)=z/√6=k
x/(√2-1)=k⇒x=k(√2-1)
y/(√2+1)=k⇒y=k(√2+1)
z/√6=k⇒z=k√6
ma=√6+√8
ma=(x+y+z)/3
√6+√8=(x+y+z)/3
x+y+z=3√6+3√8
k√2-k+k√2+k+k√6=3√6+3√8
2k√2+k√6=3(√6+2√2)
k(2√2+√6)=3(√6+2√2)
k=3
x=3(√2-1)
y=3(√2+1)
z=3√6
