Answer:
1)[tex]10^{-1}[/tex]
2)[tex]2^{-2}[/tex]
3)[tex]12^{-2}[/tex]
Step-by-step explanation:
Using negative exponent rule:
1) one -tenth of kilometer =.1 =[tex]\frac{1}{10}=10^{-1}[/tex]
Using negative exponent rule:
2) [tex]\frac{1}{4} =\frac{1}{2^{2} }=2^{-2}[/tex]
Using negative exponent rule:
3)[tex]\frac{1}{144} =\frac{1}{12^{2} }= 12^{-2}[/tex]
