Answer:
The first step is to determine the largest number that evenly divides the numerator and the denominator (also called the Greatest Common Factor of these numbers). In other words, what's the biggest number that goes into '2' (the numerator) and '4', the denominator?
Step 2. Once you've answered step 1 and realized that, for our fraction at least, the greatest number that evenly divides 2 and 4 is '2'. Now divide the top and the bottom by 2 to get your simplified fraction which is ½.
I hope this helps if you have any questions on my answer plz let me know Ty :3

Answer:
The correct option is A.
Step-by-step explanation:
The given expression is:
(a^-8b/a^-5b^3)^-3
We have to keep one thing in our mind that in a division, same base, the exponents are subtracted.
We will change the division into multiplication: The denominator will become numerator and the signs of the exponent become opposite.
(a^-8 *a^+5 * b *b^-3)^-3
=(a^-8+5 * b^1-3) ^-3
=(a^-3*b^-2)^-3
=(a)^-3*-3 (b)^-2*-3
= a^9 b^6
Thus the correct option is A....
