Question

Solve this using laws of exponents

Answer 1

Step-by-step explanation:

$\frac{25 \times {x}^{ - 4} }{ {5}^{ - 3} \times 10 \times {x}^{ - 8} }$

$\frac{ {5}^{2} \times {x}^{ - 4} }{ {5}^{ - 3} \times 2 \times 5 \times {x}^{ - 8} }$

$\frac{1}{ {5}^{ - 4} \times 2 \times {x}^{ - 4} }$

$\frac{625 {x}^{4} }{2}$
