Question

proov that 2^n+2^n-1/2^n+1-2^n=3/2​

Answer 1

Step-by-step explanation:

please write a right way

Answer 2

Take ${2}^{n}$common from numerator and as well as denominator, then we get:

$= \frac{ {2}^{n} + {2}^{n} - 1 }{ {2}^{n} + 1 - {2}^{n} }$

Take out ${2}^{n}$common, we have:

$= \frac{( {2}^{n} \times (1 + \frac{1}{2} ))}{( {2}^{n} \times (2 - 1))}$

Now, upon cancellation of ${2}^{n}$on both numerator and denominator, we have:

$= \frac{(1 + \frac{1}{2})}{(2 - 1)} \\ \\ = \frac{\frac{3}{2} }{1} \\ \\ = \frac{3}{2}$
