What is sqrt(49)?

Explanation:
Understanding square roots: a square root is a number that, when multiplied by itself, gives the original number. For 49, you ask which number times itself equals 49. Since 7 × 7 = 49, the square root is 7. The other numbers don’t work because their squares aren’t 49 (14 × 14 = 196, 49 × 49 = 2401, 3 × 3 = 9). By convention, the square root refers to the nonnegative result, so the principal root is 7.
