105 = 7. (1 - 2^n) / 1-2
105*-1 = 7 (1 - 2^n)
1 - 2^n = -105/7 = - 15
2^n = 16

The expression is an illustration of the summation notation
The expanded form of the summation notation 
is 0^4 + 1^4 + 2^4 + 3^4+4^4
<h3>How to determine the expanded form</h3>
The summation notation is given as:
The above summation notation represents the sum of the numbers raise to the power of 4, from 0 to 4
So, we have:
Hence, the expanded form of is 0^4 + 1^4 + 2^4 + 3^4+4^4
