Laws of Exponents part 1

we can expand variable with a exponent because if we have x^3 you expand it x*x*x an you get x^3. The exponent of y is one because there is one of what y stands for. x times x is x^2. The reason why it not just x is because if you have one apple that is a if you have two apples it is a^2. If you have an exponent it is telling you how many of the variable you have. I have been noticing a patten.
