You have to move the decimal four (note the exponent) places to the left so the decimal is directly after the first number. You have to drop the zero because it's not significant. The answer is 1.958 x 10^4
54 5 270
------- × ------- = --------- = 45
1 6 6
28 2 56
------- × ------ = ------- = 8
1 7 7
Answer:
15
Step-by-step explanation:
1! = 1, which contains no zeroes at the end
5! = 120, which contains 1 zero at the end
10! = 3628800, which contains 2 zeroes at the end
15! = 1307674368000, which contains 3 zeroes at the end
Therefore, the smallest value that N can have is 15
Both of the Students are correct, where the units are the same in the beginning and at the end. If you divide 20 feet by 4, you get 5 feet or 60 inches. If you convert 20 feet to inches, you get 240 inches. When you divide 240 by 4, you get 60 inches. Therefore, they both are correct.
