Question

prove 2^n+2^n-1/2n+1-2^n=3/2​

Answer 1

Answer:

THERE ARE TWO SIMPLE APPROACHES TO SOLVE THE ABOVE PROBLEM.

METHOD 1:-

PROOF :-

FIRSTLY TAKE 2^n common from numerator and as well as denominator,then

we get

= 2n+2n−12n+1−2n  

take out 2^n common,we have

= (2n∗(1+1/2))(2n∗(2–1))  

now upon cancellation of  2n  on both numerator and denominator,we have

= (1+12)(2–1)  

=321  

=32  

METHOD 2:-

PUT ANY VALUE OF  n=0,1,2,3,………….  

U SIMPLY GET

=32 .
