Explicación paso a paso:
1. [tex]17m^{2} -45m^{2} = -28m^{2}[/tex]
2. [tex]-9xy-(-8yz)=-9xy+8yz[/tex]
3. [tex]-10x^{2} y-(-3x^{2} y)= -10x^{2} y+3x^{2} y= -7x^{2} y[/tex]
4. [tex]-236ma -(-19ma)= -236ma +19ma= -217ma[/tex]
5. [tex]\frac{3}{8} m^{3} -\frac{7}{6} m^{3}= \frac{6.3m^{3}-8.7m^{3}}{8.6} = \frac{18m^{3}-56m^{3}}{48} =\frac{-38m^{3}}{48} =-\frac{19}{24}m^{3}[/tex]
