Multiple Choice

Find the product. Assume variables represent positive real numbers.
- $7 x ^ { 7 / 5 } \left( x ^ { 11 / 5 } - 6 x \right)$

A) $7 x ^ { 18 / 5 } - \frac { 42 } { x ^ { 12 / 5 } }$
B) $\frac{7}{x^{18 / 5}}-42 x^{12 / 5}$
C) $\frac { 7 } { x ^ { 18 / 5 } } - \frac { 42 } { x ^ { 12 / 5 } }$
D) $7 x ^ { 18 / 5 } - 42 x ^ { 12 / 5 }$
