ake 2880 person-hours to build a new library. If 12 workers are scheduled to work on the project at the same time how many hours will it take to complete the project?
You can first multiply your coefficients (7x9), which gives you 63. You can then simplify the exponents by using the rule that when two terms with the same variable are being multiplied, you can simplify by adding exponents. Since 7+3= 10, your simplified answer would be 63x^10 :) hope it helped!
