Answer:
B
Step-by-step explanation:
You have to know this :
=> [tex](\frac{x}{y}) ^{a}= \frac{x^{a} }{y^{a}}[/tex] =>question is asking this
[tex](\frac{x}{y}) ^{-a}= \frac{y^{a} }{x^{a}}[/tex]
[tex]x^{a} . y^{a} =(xy)^{a}[/tex]
[tex](a^{b})^{c} =a^{b.c}[/tex]
About question
[tex](\frac{7}{4}) ^{11}= \frac{7^{11} }{4^{11}}[/tex]
Hope this helps ^-^
