Answer 1

Explicación paso a paso:

$r = \frac{m {}^{7} \times m {}^{4} \times \: m {}^{6} }{m {}^{2} \times m {}^{3} } + \frac{m {}^{12} \times m {}^{5} \times m {}^{3} }{m {}^{8} }$

$r = \frac{m {}^{7 + 4 + 6} }{m {}^{2 + 3} } + \frac{m {}^{12 + 5 + 3} }{m {}^{8} }$

$r = \frac{m {}^{17} }{m {}^{5} } + \frac{m {}^{20} }{m {}^{8} }$

$r = m {}^{17 - 5} + m {}^{20 - 8}$

$r = m {}^{12} + m {}^{12}$
