Answer:
21
Step-by-step explanation:
So, factors of 6 that are between 17 and 25 are 18 and 20, so that's not the numbers.
Multiples of 3 are 18, 21, and 24.
The only number that would be reasonable enough is 21, because it is a multiple of 3 and is not a factor of 6.
To convert to scientific notation, start by moving the decimal place in the number until you have a coefficient between 1 and 10; here it is 3.45. The number of places to the left that you had to move the decimal point is the exponent. Here, we had to move the decimal 4 places to the right, so the exponent is -4.
2340000 = 2.34 x 10^6
0.000034= 3.4 x 10^-5
D≈6.37
