Radicals with the same index and radicand are known as like radicals. 6/3 = 2 and 6/2 = 3. This process is shown in the next example. 2) To multiply radicals with different indices use fractional exponents and the laws of exponents. For example, 3 with a radical of 8. In other words, when you are multiplying two radicals that have the same index number, you can write the product under the same radical with the common index number. When we multiply two radicals they must have the same index. Multiplying Square Roots Students learn to multiply radicals by multiplying the numbers that are outside the radicals together, and multiplying the numbers that are inside the radicals together. For tips on multiplying radicals that have coefficients or different indices, keep reading. For example, the multiplication of √a with √b, is written as √a x √b. 1) To multiply two or more radicals having the same index use . 4 a2b3 √ 6 a2b √ Commonindexis12. 3√2 = 6√22 = 6√4. When a radical and a coefficient are placed together, it's understood to mean the same thing as multiplying the radical by the coefficient, or to continue the example, 2 * (square root)5. So for example, in the expression 2(square root)5, 5 is beneath the radical sign and the number 2, outside the radical, is the coefficient. The common index for 2 and 3 is the least common multiple, or 6. Radicals with the same index and radicand are known as like radicals. 1) To multiply two or more radicals having the same index use .
