[tex]a) m*m^{3} - 2m*m = m^{4} - 2m^{2}[/tex]
[tex]b) 6a^{2} *(a) + 3a^{3} = 6a^{3} + 3a^{3} = 9a^{3}[/tex]
[tex]c) \frac{10x^{3} }{-2x} } - 2x^{2} = -5x^{2} - 2x^{2} = -7x^{2}[/tex]
[tex]d) \frac{x^{5} }{x} - \frac{m^{6} }{m^{3} } - 2x^{4} = x^{4} - m^{3} - 2x^{4} = -x^{4} - m^{3}[/tex]
[tex]e) \frac{15b^{6} }{-3b^{2} } + 9b^{4} = -5b^{4} + 9b^{4} = 4b^{4}[/tex]
[tex]f) -2x^{2} *-4x^{4} + (-x^{3}) ^{2} = 8x^{6} + ( -x )^{6} = 8x^{6} + x^{6} = 9x^{6}[/tex]
