  • Introduction
  • There will be an exponent rule quiz on monday. Stop by the library if you need extra tutoring!
  • Base
  • For example, in the problem 3^2 the base would be 3 because it is the number being multiplied.
  • Sure thing, lets start with the basics! An exponent consists of a base. The base is the number that tells what expression is being multiplied.
  • Hello Mr.Ma, I've been having a hard time understanding exponent rules. I was wondering if you can explain them to me for Monday's quiz!
  • Exponent
  • That's the exponent. which is the number or expression that indicates how many times a number is multiplied by itself.
  • That's spot on!
  • So the problem 7^3 the base 7 would multiply itself 3 times?
  • Ahh I see! What is the number on top of the base??
  • Product Rule
  • When multiplying expnonential expressions, the exponent is added when the base is the same.
  • Now you must now the product rule!
  • So if I was multiplying n^4 + n^5, the answer would be n^20?
  • What is that??
  • Quotient Rule
  • False. Accroding to the Quotient Rule, we actually do the opposite. Instead of adding, we subtract the exponents when the bases are the same.
  • Ohh, so in the problem a^5 divided by a^3, it would equal to a^2
  • Does that mean you also add the exponents when dividing exponential expressions?
  • Power to Power Rule
  • For example, the problem (x^4)^4 you would just multiply the exponents together which would equal to x^16
  • The power to power rule is used when an exponent is raised to another exponent, you just simply multiply them together.
  • How does the power to power rule work?
  • Incorrect. Remember, we are adding the exponents instead of multiplying. So the product would be n^9.
  • Ohh yea, I understand now!
  • That's correct! You are a very fast learner!
  • That makes sense!
