Question
Evaluate: $\frac{{{8^{ - 1}} \times {5^3}}}{{{2^{ - 4}}}}$
✓
Answer
$\frac{{{8^{ - 1}} \times {5^3}}}{{{2^{ - 4}}}}$$ = \frac{{{8^{ - 1}} \times (5 \times 5 \times 5)}}{{{2^{ - 4}}}}$
$ = \frac{1}{8} \times {2^4} \times 125$
$ = \frac{1}{8} \times 2 \times 2 \times 2 \times 2 \times 125$
$ = 2 \times 125 = 250$
$ = \frac{1}{8} \times {2^4} \times 125$
$ = \frac{1}{8} \times 2 \times 2 \times 2 \times 2 \times 125$
$ = 2 \times 125 = 250$
