Answer 1

Answer:

$i) \frac{25 \times {t}^{ - 4} }{ {5}^{ - 3} \times 10 \times {t}^{ - 8} } = {5}^{4} \times {t}^{4} \times 2$

Step-by-step explanation:

$i) \frac{25 \times {t}^{ - 4} }{ {5}^{ - 3} \times 10 \times {t}^{ - 8} } \\ = \frac{25 \times {( \frac{1}{t} )}^{4} }{ {( \frac{1}{5}) }^{3} \times 10 \times { (\frac{1}{t} )}^{8} } \\ = \frac{5 \times 5 \times \frac{1}{t} \times \frac{1}{t} \times \frac{1}{t} \times \frac{1}{t} }{ \frac{1}{5} \times \frac{1}{5} \times \frac{1}{5} \times 2 \times 5 \times \frac{1}{t} \times \frac{1}{t} \times \frac{1}{t} \times \frac{1}{t} \times \frac{1}{t} \times \frac{1}{t} \times \frac{1}{t} \times \frac{1}{t} } \\ = 5 \times 5 \times \frac{1}{t} \times \frac{1}{t} \times \frac{1}{t} \times \frac{1}{t} \times 5 \times 5 \times 5 \times \frac{1}{2} \times \frac{1}{5} \times t \times t \times t \times t \times t \times t \times t \times t \\ = 5 \times 5 \times 5 \times 5 \times t \times t \times t \times t \times 2 \\ = {5}^{4} \times {t}^{4} \times 2$
