You can put this solution on YOUR website!
-3A^2B/35A^5=-3B/35A^3
-14A^3B^2/9B^4=14A^3/-9B^2 NOW WE COMBINE ALL NUMERATORS AND DENOMINATORS
-42A^3B/-315A^3B^2 NOW WE AGAIN CANCEL COMMON TERMS AND REDUCE THE FRACTION
2/15B

When you multiply identical bases with exponents, you add the exponents (ie note: bases must be the same).
Multiply the common bases together and the constants together. When you divide bases with exponents, you subtract the exponents (ex
Divide identical bases by subtracting exponents.
Rewrite and to 1
Reduce the fraction
Here is the simplified form


Check:
Let a=1 and b=2

Plug in values



Now lets compare this to our answer
Let a=1 and b=2

Plug in values


Since these 2 answers are equal, it verifies our answer. Hope this helps.
