Question
Simplify and express the result in power notation with positive exponent.$(– 4)^5÷ (– 4)^8$
✓
Answer
$(– 4)^5$ $\therefore$ $(– 4)^8$
$ = \frac{{{{( - 4)}^5}}}{{{{( - 4)}^8}}}$
$ = \frac{1}{{{{( - 4)}^{8 - 5}}}}$
$ = \frac{1}{{{{( - 4)}^3}}}$
$ = \frac{{{{( - 4)}^5}}}{{{{( - 4)}^8}}}$
$ = \frac{1}{{{{( - 4)}^{8 - 5}}}}$
$ = \frac{1}{{{{( - 4)}^3}}}$
