Answer 1

Answer:

evaluate 4 ki power minus 3

4^-3=0.015625

Answer 2

$\large { \underline{Given:-}}$

${4}^{ - 3}$

$\large{ \underline{Solution:-}}$

$According \: to\: law \: of \: exponents \\ we \: can \: write \: {4}^{ - 3}$

${4}^{ - 3} = ( \frac{1}{ {4}^{3} } )$

$[∵ {a}^{ - m} = \frac{1}{ {a}^{m} } ]$

$But \: we \: know \: that$

$\frac{1}{ {4}^{3} } = \frac{1}{64}$

$\underline{Hence} \: {4}^{ - 3} = \frac{1}{64}$
