Question 218100: I need to understand the rules of exponents a sample question is: (-6) to the second power minus 4 to the second power.
Please can you just tell me the steps to figuring this? I have been out of school for over 25 years and don't understand this.
Thank You,

You can put this solution on YOUR website!
remember - times - = +
to the second power just means a number times itself
-6*-6=+36
4*4=+16
(-6)^2-(4)^2
36-16=20
