This video shows you how you can use exponent rules to simplify radicals and square roots. Within a few minutes and you should understand the concept.
In this video we take a deeper look at the mathematical concept of order of operations. In everything there are rules and if we don’t follow them we will not come out with the correct answer. At least in math anyway.
If we did not follow the mathematical rules of order then there would be chaos when we tried to derive an answer from a problem. This is where Order of Operations comes into play. Check out this video to understand the concepts.
