[tex]\frac{8\cdot 100^n}{2^{2n+1}\cdot 5^{2n-2}}=\frac{2^3\cdot (2^2\cdot 5^2)^n}{2^{2n+1}\cdot 5^{2n-2}}=\frac{2^3\cdot 2^{2n}\cdot 5^{2n}}{2^{2n+1}\cdot 5^{2n-2}}=\\\\\frac{2^{2n+3}\cdot 5^{2n}}{2^{2n+1}\cdot 5^{2n-2}}=2^{2n+3-(2n+1)}\cdot 5^{2n-(2n-2)}=\\\\2^{2n+3-2n-1}\cdot 5^{2n-2n+2}=2^2\cdot 5^2=(2\cdot5)^2=10^2=100[/tex]
