In our last post we talked about online math tutor, in this post we will focus on add radicals calculator. We have Add Radicals Calculator, which will help us to understand and learn about the operations on radicals. Radicals mean the numbers with the powers in the form of fractions. These fractions can be ½, 3/2, 2/5 etc. Let us consider the following addition of radicals.
Root ( 3 ) + root (3 ) = 2 root ( 3)
We say that only similar radicals are added. It means that the radials with the same radicands are added. So if we have the problem: 3* root (2) - 2* root ( 3 ) + 5 * root ( 3 ) - root ( 2) + 5
Here we will join together the radicands with root 2 one side and the radicands with root 3 on another side of the expression. Thus we get the following result:
= 2 * root ( 2) + 3 * root ( 3) + 5
Here we observe that the whole number 5 is not the part of any radical so it will neither be added to root ( 2) nor to root ( 3). So we get 5 as the separate number and it is not summed up to any of the radicals. On another hand the radicals which are similar, their coefficients are added up or their difference is calculated to get the result.
Let us take another example: root ( 18 ) + root ( 8 )
= root ( 3 * 3 * 2 ) + root ( 2 * 2 * 2 )
= 3 * root ( 2) + 2 * root ( 2)
= 5 * root ( 2) Ans.
We can always use Algebra Help, online to learn about the problems related to Algebra. Tamilnadu Board Statistics Sample Papers are also available to get time to time help on the curriculum.
