Answer:
Answer is 10
2^x-1+2^x+1=2560
2^x-1+2^x-1+2=2560
Apply Law of Algebra
2^x-1+2^x-1*2^2=2560
2^x-1(1+2^2) =2560
2^x-1=2560/5=2*2*2*2*2*2*2*2*2
2^x-1=2^9
x-1=9
Therefore:x=9+1=10

The value of x is 10.
Step-by-step explanation:
We are given ,
- For solving this question, first we write it in expanded form, such as
- Taking as common from both terms in L.H.S
- Taking from L.H.S to R.H.S and solving equation
- As we know, we get 1024 by multiplying 2 to 10 times that is so we can write in place of 1024.
- We can clearly see that base is same on both sides which is 2 and if bases are same then their powers are also same. So we can write it as,
So we get the value of x which is 10.
