Answer:
[tex](4r^4s^{-2})(-3rs^{-3})(rs)=-12r^6s^{-4}[/tex]
Explanation:
Given the expression:
[tex](4r^4s^{-2})(-3rs^{-3})(rs)[/tex]
This can be rearranged using law of multiplication (That multiplication is cummutative) to become:
[tex](4)(-3)(r^4rr)(s^{-2}s^{-3}s)[/tex]
This becomes, using the law of exponents:
[tex]-12r^{4+1+1}s^{-2-3+1}[/tex]
and finally, we have:
[tex]-12r^6s^{-4}[/tex]
