Răspuns:
b=10 c=20,86 d=0
Explicație pas cu pas:
b. [tex]\sqrt{10} -3+4-\sqrt{10}+9=\\-3+4+9= 10[/tex]
c. [tex]/5-2\sqrt{6}/+25-2\sqrt{6}+\frac{2}{3} =\\5-2\sqrt{6}+25-2\sqrt{6}+\frac{2}{3} =\\30-4\sqrt{6}+\frac{2}{3} =\\\frac{92}{3}-4\sqrt{6}= 20,86[/tex]
d.[tex]3-\sqrt{3}+\sqrt{3} +1-4=\\3+1-4=0[/tex]
