Question

simplify the following, giving your answer with a positive exponent: $\frac{3n^{-4}}{4n^{3}}div12$

Explanation:

Step1: Separar la fracción

$\frac{3n^4\cdot4n^3}{12}=\frac{3\cdot4\cdot n^4\cdot n^3}{12}$

Step2: Simplificar los coeficientes

$3\cdot4 = 12$, entonces $\frac{12\cdot n^4\cdot n^3}{12}$

Step3: Cancelar el coeficiente común

$\frac{12\cdot n^4\cdot n^3}{12}=n^4\cdot n^3$

Step4: Aplicar la regla de exponentes $a^m\cdot a^n=a^{m + n}$

$n^4\cdot n^3=n^{4 + 3}=n^7$

Answer:

$n^7$
