The property $\sqrt [ n ] { a \cdot b } = \sqrt [ n ] { a } \cdot \sqrt [ n ] { b }$ says that we can simplify radicals when the operation in the radicand is multiplication. 16: Radical Expressions and Quadratic Equations, { "16.2.01:_Multiplying_and_Dividing_Radical_Expressions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "16.2.02:_Adding_and_Subtracting_Radicals" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "16.2.03:_Multiplication_of_Multiple_Term_Radicals" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "16.2.04:_Rationalizing_Denominators" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { "16.01:_Introduction_to_Roots_and_Rational_Exponents" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "16.02:_Operations_with_Radicals" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "16.03:_Radical_Equations" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "16.04:_Complex_Numbers" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "16.05:_Solving_Quadratic_Equations" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, [ "article:topic", "license:ccbyncsa", "authorname:nroc", "adding radicals", "subtracting radicals", "licenseversion:40", "source@https://content.nroc.org/DevelopmentalMath.HTML5/Common/toc/toc_en.html" ], https://math.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fmath.libretexts.org%2FBookshelves%2FApplied_Mathematics%2FDevelopmental_Math_(NROC)%2F16%253A_Radical_Expressions_and_Quadratic_Equations%2F16.02%253A_Operations_with_Radicals%2F16.2.02%253A_Adding_and_Subtracting_Radicals, $ \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}$ $ \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} $$\newcommand{\id}{\mathrm{id}}$ $ \newcommand{\Span}{\mathrm{span}}$ $ \newcommand{\kernel}{\mathrm{null}\,}$ $ \newcommand{\range}{\mathrm{range}\,}$ $ \newcommand{\RealPart}{\mathrm{Re}}$ $ \newcommand{\ImaginaryPart}{\mathrm{Im}}$ $ \newcommand{\Argument}{\mathrm{Arg}}$ $ \newcommand{\norm}[1]{\| #1 \|}$ $ \newcommand{\inner}[2]{\langle #1, #2 \rangle}$ $ \newcommand{\Span}{\mathrm{span}}$ $\newcommand{\id}{\mathrm{id}}$ $ \newcommand{\Span}{\mathrm{span}}$ $ \newcommand{\kernel}{\mathrm{null}\,}$ $ \newcommand{\range}{\mathrm{range}\,}$ $ \newcommand{\RealPart}{\mathrm{Re}}$ $ \newcommand{\ImaginaryPart}{\mathrm{Im}}$ $ \newcommand{\Argument}{\mathrm{Arg}}$ $ \newcommand{\norm}[1]{\| #1 \|}$ $ \newcommand{\inner}[2]{\langle #1, #2 \rangle}$ $ \newcommand{\Span}{\mathrm{span}}$$\newcommand{\AA}{\unicode[.8,0]{x212B}}$, 16.2.1: Multiplying and Dividing Radical Expressions, 16.2.3: Multiplication of Multiple Term Radicals, source@https://content.nroc.org/DevelopmentalMath.HTML5/Common/toc/toc_en.html, status page at https://status.libretexts.org, $\ 3+5^{\frac{1}{2}}+7^{\frac{1}{2}}+2+6\left(5^{\frac{1}{2}}\right)$, $\ 3+2+5^{\frac{1}{2}}+6\left(5^{\frac{1}{2}}\right)+7^{\frac{1}{2}}$, $\ 5+7\left(5^{\frac{1}{2}}\right)+7^{\frac{1}{2}}$.
