Question

Which is a counterexample that disproves the conjecture?

For all real numbers n, 2^n ≥ 1.

A. n = 0
B. n = 0.5
C. n = –1
D. n = 3

Answer 1

The best and most correct answer among the choices provided from your question about conjectures is the third choice or letter C. n = -1, it is because:

2^(-1) = 0.5, which is lesser than 1 and does not agree with the conjecture. I hope it has come to your help.
