Answer:
[tex]\boxed{\sf \ \ \ \dfrac{1}{6} \ \ \ }[/tex]
Step-by-step explanation:
Hello
when you multiply by [tex]2^{-3}[/tex]
it is equivalent to divide by [tex]2^3[/tex]
so we are looking for
[tex]144*2^{-3}*12^{-1}*3^{-2}=\dfrac{144}{2^3*12*3^2}=\dfrac{9*16}{2^3*12*3^2}\\=\dfrac{3^2*2^4}{2^3*12*3^2}=\dfrac{2}{12}=\dfrac{1}{6}[/tex]
hope this helps
do not hesitate if you have any question
