Question

Divide −72a⁴b⁵c⁸ by −9a²b²c³.

Answer 1

\[\frac{- 72 a^4 b^5 c^8}{- 9 a^2 b^2 c^3}\]
\[ = \frac{- 72 \times a \times a \times a \times a \times b \times b \times b \times b \times b \times c \times c \times c \times c \times c \times c \times c \times c}{- 9 \times a \times a \times b \times b \times c \times c \times c}\]
\[ = 8 a^{(4 - 2)} b^{(5 - 2)} c^{(8 - 3)} \]
\[ = 8 a^2 b^3 c^5\]
