Question Divide. Leave your answer in exponent form. Assume that Title all variables in any denominator are nonzer Divide. Leave your answer in exponent form. Assume that Question all variables in any denominator are nonzero. \[ \frac{40 m n^{5} n^{23}}{5 m n^{4} n^{9}} \] \( 8 n^{4} \) \( 8 m n^{4} \) \( 8 m^{9} n^{22} \) \( 40 m n^{4} \)
