$frac{(6 {}^{ - 2} ) {}^{3} . {6}^{4} }{(6 {}^{ - 3}) {}^{4} } = frac{6^{ - 6}. {6}^{4} }{ {6}^{ - 12} } = frac{ {6}^{ - 6 + 4} }{ {6}^{ - 12} } = frac{ {6}^{ - 2} }{ {6}^{ - 12} } = {6}^{10}$

$frac{(a^{3}.b)^{2} .( {a}^{ - 2}b)^{4} }{(ab) {}^{ - 2} } = frac{( {a}^{6}b {}^{2} ).( {a}^{ - 8} b {}^{4} ) }{a {}^{ - 2}b {}^{ - 2} } = frac{ {a}^{ - 2} {b}^{8} }{ {a}^{ - 2} {b}^{ - 2} } = {a}^{0} {b}^{10} = {b}^{10}$

semoga membantu…
