Answer:
b. [tex]\frac{1}{10000}[/tex]
d. [tex]\frac{20}{11}[/tex]
Step-by-step explanation:
b) [tex](-100)^{-3}[/tex] ÷ [tex](-100)^{-1}[/tex]= [tex](-100)^{-3-(-1)}[/tex] we know that [tex]a^{n}[/tex]÷[tex]a^{m}[/tex]=[tex]a^{n-m}[/tex]
= [tex](-100)^{-3+1}[/tex] = [tex](-100)^{-2}[/tex]
= [tex](\frac{1}{-100} )^{2}[/tex]= [tex]\frac{1}{10000}[/tex]
d) [tex](\frac{20}{11} )^{-1}[/tex]× [tex](\frac{11}{20} )^{-2}[/tex]= [tex](\frac{20}{11} )^{-1}[/tex] × [tex](\frac{20}{11} )^{2}[/tex] we know that [tex]a^{n}[/tex]×[tex]a^{m}[/tex] = [tex]a^{n+m}[/tex]
= [tex](\frac{20}{11} )^{-1 + 2}[/tex] = [tex](\frac{20}{11} )^{1}[/tex]= [tex](\frac{20}{11} )[/tex]
