The question "ルートにはいくつ" asks: "How many roots are there?" in the context of mathematics. In mathematics, specifically regarding square roots (平方根), for a given number AAA, there are two square roots: one positive and one negative. The square root symbol \sqrt{} represents the positive root only. For example, the number 4 has two square roots: +2+2+2 and −2-2−2. However, the "root" symbol 4\sqrt{4}4 only refers to the positive root +2+2+2. Thus:
- The total number of square roots of a positive number AAA is two.
- The "root" symbol A\sqrt{A}A specifically denotes the non-negative root.
In summary, for any positive real number under the square root, there are two roots (one positive and one negative), but the root symbol \sqrt{} refers to only the positive root.
