Answer:
○ B. [tex]\displaystyle \frac{2r^4}{s^3}[/tex]
Step-by-step explanation:
First off, whenever you divide similar bases, you keep the base and subtract the exponents, so you will have this:
[tex]\displaystyle {2r^4s^{-3}}[/tex]
Now this IS the correct, but although we do not see it here, we have to deal with that negative exponent, and according to the Negative Exponential Rule [part I], you bring this part of the numerator to the denominator WHILE ALTERING THE SIGN FROM NEGATIVE TO POSITIVE, so you will have this final answer:
[tex]\displaystyle \frac{1}{b^n} = b^{-n} \\ \\ \frac{2r^4}{s^3}[/tex]
I am joyous to assist you anytime.
