Question :
Simplify :
[tex] \sf \dfrac{9a^{3}b }{3a^{2} b} [/tex]
Answer :
[tex] \sf \dashrightarrow \:\dfrac{9a^{3}b }{3a^{2} b} [/tex]
[tex] \sf \dashrightarrow \:\dfrac{9 \times a \times a \times a \times b }{3 \times a \times a \times b} [/tex]
[tex] \sf \dashrightarrow \:\dfrac{ \not{9} ^{3} \times \not{a} \times \not{a} \times a \times \not{b} }{\not{3} \times \not{a} \times \not{a} \times \not{b} }[/tex]
[tex] \sf \dashrightarrow \:\dfrac{ 3 \times a}{1}[/tex]
[tex] \sf \dashrightarrow \: 3 \times a[/tex]
[tex] \sf \dashrightarrow \:3a[/tex]
Hence answer is 3a.
