Radical Math Examples
If the instructions don t tell you that you must check your answers.
Radical math examples. If the radicand is 1 then the answer will be 1 no matter what the root is. When the radical index and the exponents of all the factors in the radicand have a common factor divide both the radical index and the exponents of the factors of the radicand by their common factor that is apply root nk a mk root n a m to obtain the smallest possible radical index. The simplest case is when the radicand is a perfect power meaning that it s equal to the n th power of a whole number. As we go remember that we must square the two sides of an equation rather than the individual terms in those two sides.
This is because 1 times itself is always 1. For example the perfect squares are. Simplifying radicals sometimes radical expressions can be simplified. And when the instructions for an exercise say to check one s answers this means that you need to show your check as part of your hand in work.
1 4 9 16 25 36 etc because 1 1 2 4 2 2 9 3 2 16 4 2 25 5 2 36 6 2 and so on. Follow the same steps to solve these but pay attention to a critical point square both sides of an equation not individual terms. Watch how the next two problems are solved. For example 3 3 3 27.
We ll start with a couple simple exercises.
