Simplify each of the following. This means that they can’t be written as the quotient of two integers. Before we do anything else, let’s look at the function and decide whether we expect the limit — if it exists (as it typically will in these problems) — will be positive or negative. . For example, =, so 9 is a square number. But don’t just start off substituting or synthetic dividing. To answer it, you need to take the number which is after the square root symbol and find its factors. We know by now how to square a number (multiply it by itself), and we know that negative numbers make a positive number when squared; a minus times a minus is a plus, remember? You may perform operations under a single radical sign.. To find the square root, the exponent needs to be an even number. For example, the principal square root of \(49\) is \(7\), which denoted \(\sqrt{49} = 7\). If the exponent of the variable is odd, subtract one from the exponent, divide it by two, and write the result to the left of the square root sign, leaving the variable inside the square root sign once, with no exponent.
