The expression given is:

$\frac{(x^3)^6}{x^5}$

To simplify this expression, we can use the power rule of exponents, which states that $(a^m)^n = a^{m \times n}$, and the division rule of exponents, which states that $\frac{a^m}{a^n} = a^{m-n}$.

Step-by-step Solution:

1. Simplify the numerator using the power rule:

   $(x^3)^6 = x^{3 \times 6} = x^{18}$

2. Now, rewrite the entire expression:

   $\frac{x^{18}}{x^5}$

3. Simplify using the division rule of exponents:

   $x^{18 - 5} = x^{13}$

Final Answer:

$\frac{(x^3)^6}{x^5} = x^{13}$
