Answer 1

Answer:

Correct Question:

Using the law of Exponential, Simplify and write the Answer in exponential Form:

$= ({ \frac{8}{5} }) ^{ - 6} \times ({ - \frac { 5}{8} }) ^{ - 2}$

Solution:

$= ({ \frac{5}{8} })^{6} \times ({ - \frac{8}{5} })^{2}$

$= ({ \frac{5}{8} })^{6} \times( \frac{64}{25} )$

$= \frac{5 \times 5 \times 5 \times 5 \times 5 \times 5 \times 64}{8 \times 8 \times 8 \times 8 \times 8 \times 8 \times 25}$

$= \frac{5 \times 5 \times 5 \times 5}{8 \times 8 \times 8 \times 8}$

$= \frac{ {5}^{4} }{ {8}^{4} }$
