2^n+2^(n-1)/2^(n+1)-2^n

• Here we take 2^n common from numerator and denominator after this the remaining part contain (1+(1/2))/(2-1)=3/2 is the answer

• ((2^n)(1+2^-1))/((2^n)(2-1))
  we can take 2^n as a common factor so cancel out 2^n from both numerator and denominator,then
  (1+(1/2))/(2-1)=3/2

• 2^n+2^n-1/2^n+1-2^n
  (a^m/a^n=a^m-n)
  so
  =2^n+2^n-1-n-1-2^n
  =2^-2
  =1/4

• 2 the power 2n

• 3/2 will be the answer

• 2^-2
  2^n will get cancelled and rest is 1/4

• 1/4
  
  because 2^n will be cancelled out and 2^(n-1-n-1)=2^-2=1/4

• {2^(n-1)(2+1)} / {2^(n-1)(2^2-2)}
  (2+1) / (4-2)
  3/2
