\(\begin{array}{l}{(a+b)^{2}=a^{2}+2 a b+b^{2}} \\ {(a-b)^{2}=a^{2}-2 a b+b^{2}}\end{array}\) 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.
Test your understanding of Radical equations & functions with these 10 questions.
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.
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.
1. When n is an even number and a>0, n√a>0, called the principal root. When n is an even number and a<0, n√a is not a real number. 2. When n is an odd number and a>0, n√a>0. When n is an odd number and a<0, n√a<0. The n in n√a (always a natural number greater than 1) is called the index or the order of the radical, and a is called the radicand.
