Answer: (6^-8/7^-12)
Step-by-step explanation:
In this type of problems, you apply the laws of indices which stated that
( a²/b²)³ =( a²×³/b²×³)
= ( a6/b6)
From this question now, applying the above principle
(6²/7³)-4
= (6²×-⁴/7³×-⁴)
= (6^-8/7^-12)
So the answer is C
third

Answer:
here is my working out to find answer, if u feel that the answer is wrong then do the reverse calculation by putting n value to the equation. hope u understood and stay safe!
