Answer 2

Answer:

b. $\frac{1}{10000}$

d.  $\frac{20}{11}$

Step-by-step explanation:

b) $(-100)^{-3}$ ÷ $(-100)^{-1}$= $(-100)^{-3-(-1)}$                      we know that $a^{n}$÷$a^{m}$=$a^{n-m}$

= $(-100)^{-3+1}$ = $(-100)^{-2}$

= $(\frac{1}{-100} )^{2}$= $\frac{1}{10000}$

d) $(\frac{20}{11} )^{-1}$× $(\frac{11}{20} )^{-2}$= $(\frac{20}{11} )^{-1}$ × $(\frac{20}{11} )^{2}$                              we know that $a^{n}$×$a^{m}$ =  $a^{n+m}$        

=  $(\frac{20}{11} )^{-1 + 2}$ =   $(\frac{20}{11} )^{1}$= $(\frac{20}{11} )$
