Answer :

Answer:

Step-by-step explanation:

[tex]\[ \frac{16^3 b^5}{-2a^4 b^{-2}} \]\[ = \frac{16^3 b^5}{-2a^4 \cdot \frac{1}{b^2}} \]\[ = \frac{16^3 b^5 \cdot b^2}{-2a^4} \]\[ = \frac{16^3 b^{5+2}}{-2a^4} \]\[ = \frac{16^3 b^7}{-2a^4} \]\[ = \frac{4096 b^7}{-2a^4} \]\[ = -2048 \frac{b^7}{a^4} \][/tex]
