$tt 12 {a}^{4} {b}^{6} times 5 {a}^{5} {b}^{2}$

$= tt (12 times 5) {a}^{4 + 5} {b}^{6 + 2}$

$= tt 60 {a}^{9} {b}^{8}$

____________

$= tt frac{ 60 {a}^{7} {b}^{12} {c}^{5}}{5 {a}^{6} {b}^{3} {c}^{}}$

$= tt frac{60}{5} {a}^{7 - 6} {b}^{12 - 3} {c}^{5 - 1}$

$= tt 12 {a}^{} {b}^{9} {c}^{4}$

$tt frac{ ( {3}^{} {a}^{4} {b}^{2} {c}^{5}) {}^{5} }{(2 {a}^{3} {b}^{3} {c}^{2}){}^{3} }$

$= tt frac{ {3}^{5} {a}^{4 times 5} {b}^{2 times 5} {c}^{5 times 5}}{{2}^{3} {a}^{3 times 3} {b}^{3 times 3} {c}^{2 times 3}}$

$= tt frac{ 243 {a}^{20} {b}^{10} {c}^{25}}{8 {a}^{9} {b}^{9} {c}^{6}}$

$= tt frac{243}{8} {a}^{20 - 9} {b}^{10 - 9} {c}^{25 - 6}$

$= tt 30,375 : {a}^{11} {b}^{} {c}^{19}$
