Jigsaw Team 3
Your group will be responsible for developing the rules for dividing exponents
x^n means that x is multiplied by itself “n” times
3^4 = 3 x 3 x 3 x 3 = 81 The base is 3 and the exponent is 4: “3 to the fourth power”
x^3 = x * x * x The base is x and the exponent is 3: “x to the third power”
What if you wanted to divide x^5 by x^3 ? You would get:
X^5/x^3 = x x x x x / x x x = x^2
Directions: Write out each of the following the long way, as seen above. Then, with your team, look for a pattern and create a “short cut”.
1. x^8/x^4
2. x^6/x^2
3. m^10/m^4
4. a^2/a^5
Directions: Simplify the following using the short cut you discovered above.
1. x^80/x
2. x^20/x^2
3. m^10/m^400
4. a^20/a^20
In your own words, write out the rule for dividing expressions containing an exponent. Your team must come to a consensus about this rule. Post your rule on the class Edmodo page.
