Question

(1/2)-³×(1/4)-³×(1/5)-³​

Answer 1

Step-by-step explanation:

${ (\frac{1}{2} )}^{ - 3} \times {( \frac{1}{4} )}^{ - 3} \times {( \frac{1}{5}) }^{ - 3} \\ = \frac{ {1}^{ - 3} }{ {2}^{ - 3} } \times \frac{ {1}^{ - 3} }{ {4}^{ - 3} } \times \frac{ {1}^{ - 3} }{ {5}^{ - 3} } \\ = \frac{ {2}^{3} }{ {1}^{3} } \times \frac{ {4}^{3} }{ {1}^{3} } \times \frac{ {5}^{3} }{ {1}^{3} } \: \: \: \: \: \: ( {a}^{ - n} = \frac{1}{ {a}^{n} } \: \: \: \frac{1}{ {a}^{ - n} } = {a}^{n} ) \\ = {2}^{3} \times {4}^{3} \times {5}^{3} \\ = 8 \times 64 \times 125 \\ = 64000$
