Odpowiedź:
a
[tex]3*3+4=9+4=13[/tex]
[tex]3*(-2)+4=-6+4=-2[/tex]
[tex]3*\frac{1}{6} +4=\frac{3}{1}*\frac{1}{6} +\frac{4}{1}=\frac{1}{2}+ \frac{4}{1}=\frac{1}{2}+ \frac{8}{2}=\frac{9}{2} =4\frac{1}{2}[/tex]
b
[tex]-2*2+3^{2} =-4+9=5\\[/tex]
[tex]-2*(-4)+5^{2}=8+25=33[/tex]
[tex]-2*\frac{5}{8}+0.5^{2}=\frac{-2}{1}*\frac{5}{8}+0.5^{2}=\frac{-1}{1}*\frac{5}{4}+0.25=\frac{-5}{4}+0.25=-1\frac{1}{4}+0.25=-1\frac{1}{4}+\frac{1}{4}=-1[/tex]
