Answer:
2.13% (rounded to nearest thousandth)
Step-by-step explanation:
You subtract 24 from 23.5 to get 0.5
Then you divide 0.5 by 23.5 to get 0.02127
Then you multiply that by 100 to get your percent error
12.34 - 10.778 = 1.562
The nearest tenth is 1.6 .
Note that both 5 and 4 are exponents, and their product is 5*4=20, or 4*5=20. Thus,
(3^5)^4 is equal to (3^4)^5
Review:
(a to the power b)to the power c = a to the power bc.
Thus, (3 to the power 5)^4 = 3^20; the same is true if you reverse the positions of the 5 and the 4.
