Simplify the following
​

Answer 1

Step-by-step explanation:

$\frac{27 \times {a}^{ - 4} }{12 \times {4 }^{ - 3} \times {a}^{ - 5} } = \frac{27 \times \frac{1}{ {a}^{4} } }{12 \times \frac{1}{ {4}^{3} } \times \frac{1}{ {a}^{5} } } = \frac{27 \times {4}^{3} \times {a}^{5} }{12 \times {a}^{4} } \\ = 9 \times 16 \times a = 144a$
