## Related Books You can simplify a radical expression by removing perfect-square factors from the radicand (the quantity or expression under the radical sign). Multiplication Property of Square Roots: For every number a?0 and b?0, ?ab=?a??b Example: ?54=?9??6=3??6=3?6 You can use the Multiplication Property of Square Roots to simplify radical expressions by rewriting the radicand as ...

###### Radical Equations with Extraneous Solutions Radical equations with square roots often have extraneous solutions because through the process of solving these equations we must square both sides of the equation. However, the process of squaring both sides is not a “reversible” operation. For instance, (?2) =4, but 4=2. We can’t get back to ?2. This is why it is so important to check proposed solutions in the original equation to ...

###### Fractional Exponents and Radical Expressions The laws of exponents suggest an exponential notation for roots involving fractional exponents. For instance, applying the exponent rules to the expression a1/2, we get Thus, a1/2 should be the number whose square is a, so we define Similarly, we define The Exponent Laws Work for Fractional Exponents The exponent laws also work for fractional exponents. 1 of 9. Example 2 Evaluate (a) 251/2 (b ... Page 1 of 2 438 Chapter 7 Powers, Roots, and Radicals Solving an Equation with One Radical Solve 4x º 7+ 2 = 5.

If x and y are two elements in these sets and if a relation exists between x and y, then x ... The function g(x) is not defined at x=2 or x=-2. c) h(t) is the square root of 4-3t. Only nonnegative numbers have real square roots, so the expression on the radical must be ?0. 4 – 3t ?0-3t ?-4 Remember when you multiply an inequality by a ...

###### Square Roots and Other Radicals - UIS Square Roots and Other Radicals Sponsored by The Center for Teaching and Learning at UIS Page | 1 Radicals - Definition Radicals, or roots, are the opposite operation of applying exponents. A power can be undone with a radical and a radical can be undone with a power. For example, if you square 2, you get 4, and if you take the square root of 4, you get 2; if you square 3, you get 9, and if ...

Key Terms Use the vocabulary terms listed below to complete each statement in Exercises 1–4. principal ... RD.1 Radical Expressions, Functions, and Graphs . Roots and Radicals . The operation of taking a square root of a number is the reverse operation of squaring a number. For example, a square root of 25 is 5 because raising 5 to the second power gives us 25. Note: Observe that raising ?5 to the second power also gives us 25. So, the square root of 25 could have two answers, 5 or ?5. To avoid ...
