Answer :
Hello.
Remember the Property of exponents:
[tex]\mathrm{\displaystyle\frac{a^{m} }{a^{n} } =a^{m-n}}[/tex]
Let's use it to solve our maths problem.
[tex]\mathrm{\displaystyle\frac{c^{4} }{c^{3} } =c^{4-3} }[/tex]
Subtract the exponents:
[tex]\mathrm{c^{1} =c}[/tex]
Therefore, the answer is
c.
I hope it helps.
Have a nice day.
