I’ve gotten 4 different answers for this so if someone can help me that would be amazing

Simplifying the top:

(2* a^3 * b^5)^2 * (6ab)

4* a^6 *b^10 * (6ab)

24 *a^7 * b^11

so we have

(24 *a^7 * b^11) / (-3* a^5 *b)

immediately we can simplify 24 and -3

(-8 *a^7 * b^11) / ( a^5 *b)

a^7 and a^5 can cancel into just a^2

(-8 *a^2 * b^11) / (b)

b^11 and b cancels to b^10

-8 *a^2 * b^10

so that is your

-8

sine
