$\sf2 {m}^{4} \times {m}^{ - 3}$

$\sf2( {m}^{4} \times {m}^{ - 3} )$

$\sf2( {m}^{4 + ( - 3)} )$

$\sf2( {m}^{4 - 3} )$

$\bf\blue{2 {m}^{1} }$

$\sf\frac{ {6}^{7} }{ {6}^{3} }$

$\sf{6}^{7} \div {6}^{3}$

$\sf{6}^{7 - 3}$

$\bf\blue{ {6}^{4} }$

$\sf\frac{ {b}^{ - 6} }{ {b}^{ - 3} }$

$\sf{b}^{ - 6} \div {b}^{ - 3}$

$\sf{b}^{ - 6 - ( - 3)}$

$\sf{b}^{ - 6 + 3}$

$\sf{b}^{ - 3} = \bf\blue{\frac{1}{ {b}^{3} } }$

Penyelesaian :

$1.) \: \: 2m^{4} \times m^{ - 3} \\ =2( {m}^{4} \times m³) \\ = 2(m ^{4-3}) \\ \sf{ \blue{= 2m¹} }\\ \\ \\ 2.) \: \: \frac{6^{7} }{6^{3} } \\ = {6}^{7} ÷ {6}^{3} \\ = 6 ^ {7-3} \\ \sf{ \blue{= {6}^{4} }}\\ \\ 3.) \: \: \frac{b^{ - 6}}{b^{ - 3}} \\ \sf{\blue{ = {b}^{ - 6} \div {b}^{ - 3} }} \\ \sf{ \blue{ = {b}^{(-6)-(-3)} }} \\ \sf{\blue{ = {b}^{ 3} }}$
