To simplify the expression
\[ \frac{r^2 \times r^6 \times r}{r^3} \]
we can start by combining the terms in the numerator.
- Combine the powers of \( r \) in the numerator:
\[ r^2 \times r^6 \times r = r^{2+6+1} = r^9 \]
So, the numerator simplifies to \( r^9 \).
- Now, rewrite the expression:
\[ \frac{r^9}{r^3} \]
- Apply the property of exponents (subtract the exponents when dividing):
\[ \frac{r^9}{r^3} = r^{9-3} = r^6 \]
The simplified expression is:
\[ \boxed{r^6} \]
