(1+1/1)(1+1/2)(1+1/3)(1+1/n)=n+1

(2/1 )(3/2)(4/3)...(n-1/n-2)(n/n-1)(n+1/n) = n + 1

n + 1 = n + 1

1 = 1 ( Fact )

Thus it is not importent what the value of n is at all because the equation is always have the equal number ( which is 1 ) in both sides .

Step-by-step explanation:

(2/1 )(3/2)(4/3)...(n-1/n-2)(n/n-1)(n+1/n) = n + 1

n + 1 = n + 1

1 = 1 ( Fact )
