MCQ - 10-3986

Question:

If the square root of t is a real number, is the square root of t positive?

(1) t > 0

(2) t² > 0

Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.

Correct Answer: E

Explanation:

This question is looking for a definite yes or no answer. Statement (1) is not sufficient since all it tells us is that t is a positive number. Unless the square root is taken, a positive number has two square roots, a positive root and a negative root. For example, if t is 4, then it has two square roots, 2 and –2. So we can eliminate A and D.
