Isolate the radical. \(\sqrt{r+4}=r-2\) Square both sides of the equation. \((\sqrt{r+4})^{2}=(r-2)^{2}\) Simplify and then solve the equation. \(r+4=r^{2}-4 r+4\) If it is a quadratic equation, so get zero on one side. \(0=r^{2}-5 r\) Factor the right side. \(0=r(r-5)\) Use the Zero Product Property. \(0=r \quad 0=r-5\) Solve the equation. \(r ...
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.
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.
