Sederhanakan dan nyatakan dengan eksponen positif

Jawaban:

$f. {a}^{ - 6} {b}^{4} times {a}^{2} {b}^{ - 2} = {a}^{ - 4} {b}^{2} = frac{ {b}^{2} }{ {a}^{4} } \ \ g.4 {m}^{7} n ^{ - 4} times 2m ^{ - 6} n ^{ - 3} = 2m {n}^{ - 7} = frac{2m}{ {n}^{7} } \ \ h. frac{8a ^{ - 6} }{ {2a}^{4} } = 4 {a}^{ - 10} = frac{4}{ {a}^{10} } \ \ \ i. frac{56 t^{5} }{ {7t}^{ - 2} } = 8 {t}^{7} \ \ j.( frac{8 {x}^{2} {y}^{3} }{ {16x}^{5} y} ) ^{3} = frac{8 ^{3} {x}^{2} {y}^{9} }{ {16}^{3} {x}^{15} {y}^{3} } = frac{ {x}^{ - 13} {y}^{6} }{ {2}^{3} } = frac{ {y}^{6} }{ {2}^{3} {x}^{13} } \ \ k.( frac{5 {q}^{ - 2} }{ {h}^{3} } ) ^{ - 2} = frac{ {5}^{ - 2} {q}^{ 4} }{ {h}^{ - 6} } = frac{ {h}^{6} {q}^{4} }{ {5}^{2} } = frac{ {h}^{6} {q}^{4} }{25} \ \ l.( {3a}^{2} b ^{ - 3} ) ^{3} times (2 {a}^{4} ) ^{ - 2} = {3}^{3} {a}^{6} b ^{ - 9} times {2}^{ - 2} {a}^{ - 8} = {3}^{3} {a}^{ - 2} {b}^{ - 9} times {2}^{ - 2} = frac{ {3}^{3} }{ {a}^{2} b ^{9} {2}^{2} }$
