1) =2³*(5²*2²)^n/2^(2n+1)*5^(2n-2)=2^(3+2n-2n-1)*5^(2n-2n+2)=2²*5²=4*25=100
2)=2²*(2*3)^2n/3^(2n-3)*2^(2n+2)=2^(2+2n-2n-2)*3^(2n-2n+3)=2^0*3³=1*27=27
3)=2²*(3²*2)^n/3^(2n-1)*2^(n+1)=2^(2+n-n-1)*3^(2n-2n+1)=2*3=6
4)=2^(2n-1)*3^(n+1)/(2*3)*(2²*3)^n=2^(2n-1-1-2n)*3^(n+1-1-n)=2^(-2)*3^0=1/2²*1=1/4
5)=5^(n+1)-5^(n-1)/2*5^n=5^n(5-5^(-1))/2*5^n=(5-1/5)/2=24/5:2=24/5*1/2=24\10=2,4
6)=10*2^n/(2^(n+1)+2^(n-1)=10*2^n/2^n(2+2^(-1))=10/(2+1/2)=10:5/2=10*2/5=4
