WebbC. Simplifying Radicals 1. First simplify the coefficient root. 2. To simplify the variables, use the “divide and remainder” trick: divide the power by the index; the quotient is the power that comes out and the remainder is the power that stays in. Note: For simplicity, we will assume during the next few sections that all variables rep- WebbNow let us move to simplifying fourth degree roots. No matter what root you are simplifying, the same idea applies: find cubes for cube roots, powers of four for fourth roots, etc. Recall that when your simplified expression contains an even indexed radical and a variable factor with an odd exponent, you need to apply an absolute value. Example
WebbYou ask a good question and you are right in your thinking. By definition, the Principal root of a number is the same sign as the real number. For example, both -4 and +4 are the square roots of 16. So, to talk about just the principal root of 16 means we discuss the "n"th root of 16 that has the "same sign" as the number in question. Since 16 is positive, the … WebbSimplifying Fourth Roots. The fourth root of a number x is a number y, such that y 4, or y multiplied by itself 4 times, gives x. Often times, the fourth root of a number is an irrational number, which means that we can't write its exact value in decimal form. When this is the case, we can simplify the fourth root as much as possible to get its ...
