[tex]\textsf{Given,}\\[/tex]
[tex] \sf{ \frac{ {a}^{6} {b}^{4} }{ {a}^{2} {b}^{3} } } \\ [/tex]
[tex]\textsf{Using law of intergal expo.. aᵐ ÷ aⁿ = aᵐ - ⁿ}\\[/tex]
[tex] \sf{ \Rightarrow \: {a}^{(6 - 2)} {b}^{(4 - 3)} } \\ [/tex]
[tex] \sf{ \Rightarrow \: {a}^{4} {b}^{1} } \\ [/tex]
[tex] \sf{ \Rightarrow \: {a}^{4} {b}^{} } \\ [/tex]
