Question

Which expression is equivalent to( a -^8 b/a -^5 b^3)-^3? Assume a~0,b~0 .

Answer 1

Answer:A edg

Explanation:

Answer 2

For this case we have the following expression:
(a ^ -8b / a ^ -5b ^ 3) ^ - 3
For power properties we have:
((a ^ (- 8 - (- 5))) (b ^ (1-3))) ^ - 3
Rewriting we have:
((a ^ (- 8 + 5)) (b ^ (- 2))) ^ - 3
((a ^ (- 3)) (b ^ (- 2))) ^ - 3
For power properties we have
(a ^ 9) (b ^ 6)
Answer:
(a ^ 9) (b ^ 6)
