[tex]8 \sqrt{75} - 5 \sqrt{48} [/tex]
[tex]8*5 \sqrt{3} - 5*4 \sqrt{3} = 40 \sqrt{3} - 20 \sqrt{3} = 20 \sqrt{3} \\ \\ \frac{8,5}{100} * \frac{20 \sqrt{3} }{1} = \frac{170 \sqrt{3} }{100} = 1,70 \sqrt{3}[/tex]
Numarul cu 8,5% mai mare decat diferenta este :
[tex]20 \sqrt{3} + 1,70 \sqrt{3} = 21,70 \sqrt{3} [/tex]
Cred ca am facut bine. Sper ca ai inteles. Succes!
