Question

daca (x)/(3y)=0.5,sa se afle valuarea raportului (x^2)/(y^2)

Answer 1

[tex]\frac{x}{3y} =0,5 => \frac{1}{3} * \frac{x}{y} =0,5 \\ \\ => \frac{x}{y} = 0,5*3 => \frac{x}{y} =1,5 \\ \\ Ridicam-totul-la-puterea-a-2-a \\ \\ => \frac{ x^{2} }{y^{2}}=1,5^{2} \\ \\ => \frac{ x^{2} }{y^{2}}=2,25[/tex]
