Question

2^n-1+2^n+1=320
please solve this question it is very important for me​

Answer 1

Step-by-step explanation:

$2^{n-1} + 2^{n+1}=320$

$2^n(2^-1+2^1)=320$

$2^n(1/2 +2) =320$

$2^n(5/2)=320$

$2^{n-1} \times 5=320$

$2^{n-1}= 320/div 5$

$2^{n-1}= 64$

$2^{n-1}= 2^6$

since bases are same thus power must be equal

$n-1=6$

$n=7$

Answer 2

Answer:

n=7
