It gives you step by step solutions along with explanations. Here is a set of practice problems to accompany the Rational Expressions section of the Preliminaries chapter of the notes for Paul Dawkins Algebra course at Lamar University. The reason we raise the equation to the reciprocal of the exponent is because we want to eliminate the exponent on the variable term, and a number multiplied by its reciprocal equals 1. 2. The way to remove the exponent on x is by raising both sides of the equation to a power that is the reciprocal of [latex]\frac{5}{4}[/latex], which is [latex]\frac{4}{5}[/latex].

How to Simplify a Division Expression Video amp Lesson. It is easy to find the cube root of 8, so rewrite [latex]{8}^{\frac{2}{3}}[/latex] as [latex]{\left({8}^{\frac{1}{3}}\right)}^{2}[/latex]. A rational exponent indicates a power in the numerator and a root in the denominator. For example, to solve x^(1/2) = 6, we take both sides to the reciprocal power on the x, which is 2/1, or 2, and we have x = 6^2, or x = 36. From free multiple choice math worksheets to trigonometry, we have all the details included. Where did [latex]{x}^{\frac{1}{4}}[/latex] come from?

Simplify Exponents Multiple Choice Questions PRAXIS CORE Get 55 Free Practice Questions Now 2018 w. Math Questions Math Answers Solving Math Problems. For example, to solve x^(1/2) = 6, we take both sides to the reciprocal power on the x, which is 2/1, or 2, and we have x = 6^2, or x = 36. For example, [latex]\frac{2}{3}\left(\frac{3}{2}\right)=1[/latex], [latex]3\left(\frac{1}{3}\right)=1[/latex], and so on. Occasionally, a value of the variable that appears to be a solution will make one or more of the denominators zero. (a) 0 (b) 9 4 (c) 7 4 (d) Undefined 3. I remember that some time ago I too had to go through a similar period of worry . Solve the problem. Therefore, if we multiply [latex]{x}^{\frac{2}{4}}[/latex] back in using the distributive property, we get the expression we had before the factoring, which is what should happen. After you're corrected the required setting(s) refresh/reload this page. METHOD: Isolate the radical. Simplifying Expressions with Rational Exponents Study com. Then, factor out [latex]{x}^{\frac{2}{4}}[/latex] from both terms on the left. The online math tests and quizzes on positive, negative and rational exponents. We need an exponent such that when added to [latex]\frac{2}{4}[/latex] equals [latex]\frac{3}{4}[/latex].

Textbook Authors: Hall, Prentice, ISBN-10: 0133186024, ISBN-13: 978-0-13318-602-4, Publisher: Prentice Hall It will not aid you in understanding the subject. Notice how the fractional exponent on the left side becomes an exponent of 1. Solving Rational Equations. Cookies are not enabled on your browser. First, put the variable terms on one side of the equal sign and set the equation equal to zero. Radical equations may have one or more radical terms and are solved by eliminating each radical, one at a time. I however would warn you not to just copy the answers from the software. We can solve equations in which a variable is raised to a rational exponent by raising both sides of the equation to the reciprocal of the exponent. Textbook Authors: Hall, Prentice, ISBN-10: 0133186024, ISBN-13: 978-0-13318-602-4, Publisher: Prentice Hall exponents, evaluate and simplify algebraic expressions with integral exponents, and simplify rational algebraic expressions. I can rewrite expressions involving radicals and rational exponents using the properties of exponents. The reason we raise the equation to the reciprocal of the exponent is because we want to eliminate the exponent on the variable term, and a number multiplied by its reciprocal equals 1.
