A) \[\frac{-24}{{{n}^{3}}}\]
B) \[{{\left( -\frac{3}{4} \right)}^{4}}\]
C) \[\frac{{{\left( -2 \right)}^{4}}}{{{n}^{4}}}\]
D) \[\left( \frac{-3}{n} \right)\times \left( \frac{-3}{n} \right)\]
Correct Answer: B
Solution :
(b) \[{{a}^{m}}\div {{b}^{m}}={{\left( \frac{a}{b} \right)}^{m}}\Rightarrow {{\left( -3 \right)}^{4}}\div {{n}^{4}}\] \[={{\left( \frac{-3}{n} \right)}^{4}}\]
