Radical Equations. A radical equation is any equation that contains one or more radicals with a variable in the radicand. Following are some examples of radical equations, all of which will be solved in this section: √x − 1 = 5 √2x − 5 + 4 = x 3√x2 + 4 − 2 = 0.
A radical expression is said to be in standard form if the following conditions hold: 1. The radicand is positive. 2. The radical index is as small as possible. 3. The exponent of each factor of the radicand is a natural number less than the radical index. 4. There are no fractions in the radicand. 5.
Since we don’t have to write 2 as an index, the answer is √j. Example 1: Write √15 as an expression with fractional exponents. Solution: The index of √15 is 2, and we have 1 as the power of the radicand. Therefore, our fractional exponent is ½. Thus, √15 = 15 1/2. Example 4: Write a 3/4 as a radical expression.
5 sty 2023 · \(\begin{array}{l}{(a+b)^{2}=a^{2}+2 a b+b^{2}} \\ {(a-b)^{2}=a^{2}-2 a b+b^{2}}\end{array}\) Solve a Radical Equation. Isolate one of the radical terms on one side of the equation. Raise both sides of the equation to the power of the index. Are there any more radicals? If yes, repeat Step 1 and Step 2 again. If no, solve the new equation.
A basic strategy for solving radical equations is to isolate the radical term first, and then raise both sides of the equation to a power to remove the radical. (The reason for using powers will become clear in a moment.)
