How to multiply radicals with different index?
We have learned how to solve radical equations by multiplying the radical with the index of the radical. We have also seen that when solving radical equations for square roots, the index of the radical can be 1, -1, or -√2. The same can be said for cube roots and tetrahedral roots. However, not all radicals have the same index for multiplying them. At times, the index of the radical will switch when the radical is multiplied with other radicals.
How to multiply radicals with different indices?
To multiply two radicals with different indices, you first need to find the product of their radical roots. Once you have the product of the radical roots, you can use the index method to find the product of the original radicals.
How to add radicals with different indices?
The good news is that adding of radicals with different indices can be done using the same properties/syntax as addition of numbers. The complexity of the problem arises as the two radicals can be of different types: one can be a radical expression, while the other can be a fraction. In this article, I will cover two different ways to add two radicals with different indices.
How to multiply radicals with sum of indices?
Let’s take your algebra problem in which you are given two different radicals with different index sums and need to find the product of the two radicals. You can get the product by multiplying the two radicals in the index sum that is the least common. For example, if you have the radical expressions a^2 – 2b and b^2 – 2c, you will need to multiply b² – 2bc. To do so, you need to find the least common denominator of the
How to add radicals together with different indices?
If you want to add two radicals with different indices, first you need to find the common index. For example, if you want to add two radicals with the index 8 and the index 15, first you need to find the index that they share. You would do this by subtracting the smaller index from the larger index. In this example, the smaller index is 8 and the larger index is 15. Therefore, subtract 8 from 15 to find the shared index. In this case, the shared index
