This week, I have learned how to add radicals. At first, I thought it would be hard because adding fraction is harder than multiplying fraction. However, it was very easy. It has the same concept as fraction.
Let’s try an example.
+
For fraction, you leave the denominator and add the top, for radicals, you add the coefficient and leave the radicand alone. So it should look something like this
+
=
Let’s try something harder
+
To be able to add, you must have the same radicand. It can’t be two different numbers. So we need to simplify it to see if we are able to add.
=
=
=
=
Because both have the same radicand, we are able to add both together.
+
=
If we have two different radicand, we can not add together.
+
Even though it is very tempting to add both together, we can not.
The final answer should be for this equation is +
