8 \sqrt{75} - 5 \sqrt{48}

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}

Numarul cu 8,5% mai mare decat diferenta este :

20 \sqrt{3} + 1,70 \sqrt{3} = 21,70 \sqrt{3}

Cred ca am facut bine. Sper ca ai inteles. Succes!
