Using Exponent Rules To Simplify Exponential Expressions

This tutorial reviews how to simplify exponential expressions containing exponents. Some examples show expressions that have like bases that are being multiplied and you have to add their exponents. Other examples show expressions with like bases that are being divided and you have to subtract their exponents. Also view examples when an exponent is being raised by another exponent such as (3x^2)^2, When an exponent is raised to a power, you will have to multiply the exponents.

I have been re-reading and re-reading the stupid book we are using, trying to figure out what the hell i was supposed to do for a week now. I watch your video and it was clear as day. Thank you soo much!

I'm much confused... I thought you for the x values you multiply the matching coefficients 2 x 3 = 6, then add the exponents to make the answer 6x^6. Then the y value would be 2y^5. I don't get why you multiplied all the exponents when they're not the same.

I see that you multiplied 2x^3 and 3x^3 which makes sense because they have the same variable. But why did you multiply 2y^2 if its not the same variable?

I honestly wish you were my math teacher

Is there a more in depth video about this...the video was great I still don't know how to write expressions in exponential notations with negative exponents divided by a different variable with negative exponents

what if the x value for the last equation is negative? Does the 27 stay in the numerator or does it also go to the denominator?

I agree, I couldn't figure it out for the life of me and after this I get it! Sorry about Rexxit below. Every one else understands now! Thank you so much for breaking it down easily!
