Answer:

4−3=2−6(base2)

Step-by-step explanation:

\begin{gathered}4^{-3}\\=\left(2^{2}\right)^{-3}\\=2^{2\times (-3)}\end{gathered}4−3=(22)−3=22×(−3)

\begin{gathered}By \: Exponential \: Law:\\\boxed {\left(a^{m}\right)^{n}=a^{mn}}\end{gathered}ByExponentialLaw:(am)n=amn

=2^{-6}\: (base \:2)=2−6(base2)

Therefore,

4^{-3}=2^{-6}\: (base \:2)4−3=2−6(base2)
