Simplifying radicals: Using exponent rules to simplify radicals or square roots

SCIENTIFIC NOTATION

Do you like powers? Sometimes, they are very useful!

Imagine we have to use these kind of numbers:
400000000000000000000000000000000000000000000000
0,0000000000000000000000000000000000000003
Wow, what a nightmare!

Let's see a very important application of powers...
