The square of 1 + 1 / 2 + 1 / 2 + the third power of 1 / 2 +100th power of 1 / 2 = (process)

The square of 1 + 1 / 2 + 1 / 2 + the third power of 1 / 2 +100th power of 1 / 2 = (process)

Add a 1 / 2 ^ 100
1+1/2+1/2^2+1/2^3…… +1/2^100+1/2^100
=1+1/2^2+.+1/2^99+1/2^99
.
=1+1/2+1/2
=2
So the square of 1 + 1 / 2 + 1 / 2 + the third power of 1 / 2 +100th power of 1 / 2 = 2-1 / 2 ^ 100
