Answer:
256/81
Step-by-step explanation:
According to the formula:
[tex]a^{-b}=1/a^{b}[/tex]
Using the above formula to solve the question, we perform following steps:
[tex](-3/4)^{-4}=1/(-3/4)^{4}[/tex]
=[tex]4^{4}/(-3)^{4}[/tex]
=[tex](4*4*4*4)/(-3*-3*-3*-3)[/tex]
=[tex]256/81[/tex] which is the required answer.
