For instance, relating cubing and cube-rooting, we have: ".

On the other hand, we may be solving a plain old math exercise, something having no "practical" application.

For example, replacing with gives on the left but gives on the right.

0$ $\sqrt=\frac$) and you get $\frac=\frac=\frac$ None of the answers proposed is correct: we can use the squared value we have calculated $\frac=\frac \frac$ As you can see it is not rational, so you exclude $1$ and $2$ Then $(6 \pm \sqrt)^2= 36 35 \pm 12 \sqrt$ and you can see that both of them are incorrect.

Square roots of negative numbers expressed as multiples of i (imaginary numbers).

is an important section of mathematics that deals with many practical applications of mathematics and it also has its applications in other fields such as computing.

To simplify this sort of radical, we need to factor the argument (that is, factor whatever is inside the radical symbol) and "take out" one copy of anything that is a square.

That is, we find anything of which we've got a pair inside the radical, and we move one copy of it out front.

When doing this, it can be helpful to use the fact that we can switch between the multiplication of roots and the root of a multiplication.

In other words, we can use the fact that radicals can be manipulated similarly to powers: .
