Be looking for powers of 4 in each radicand. Multiplication of radicals. To create this article, 16 people, some anonymous, worked to edit and improve it over time. 2) To multiply radicals with different indices use fractional exponents and the laws of exponents. Can I multiply a number inside the radical with a number outside the radical? Note: When multiplying radicals with different indexes, change to rational exponents first, find a common denominator in order to add the exponents, then rewrite in radical notation as shown below: Example: 8 ˚ 2 Multiplying radicals with coefficients is much like multiplying variables with coefficients. How do you multiply #(sqrt(a) +sqrt(b))(sqrt(a)-sqrt(b))#? Click here to review the steps for Simplifying Radicals. Examples. To multiply 4x ⋅ 3y we multiply the coefficients together and then the variables. One thing we are allowed to do is reduce, not just the radicand, but the index as well. This article has been viewed 500,141 times. If the radicals have the same index, multiply terms the outside the radical with terms outside the radical and terms inside the radical with terms inside the radical. To multiply the radicals, both of the indices will have to be 6. 3√2 = 6√22 = 6√4. Like radicals can then be added or subtracted in the same way as other like terms. If not, then you cannot combine the two radicals. We multiply radicals by multiplying their radicands together … {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/5\/5e\/Multiply-Radicals-Step-1-Version-2.jpg\/v4-460px-Multiply-Radicals-Step-1-Version-2.jpg","bigUrl":"\/images\/thumb\/5\/5e\/Multiply-Radicals-Step-1-Version-2.jpg\/aid1374920-v4-728px-Multiply-Radicals-Step-1-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"
