Simplify. Assume that variables in the exponent represent nonzero integers and that all other variables are not 0.
-$\frac { y ^ { 7 x + 7 } } { y ^ { 4 x } }$
A) $y ^ { 10 x }$
B) $y ^ { 3 x + 7 }$
C) $y ^ { 18 x }$
D) $y ^ { 11 x + 7 }$

To simplify the expression, use the quotient rule for exponents: $a^m / a^n = a^{m-n}$. Applying this rule here gives $y^{(7x+7)-(4x)} = y^{3x+7}$.
