Answer:
C. 0.0067
Step-by-step explanation:
6.7*10^-3
Write in standard form.
This question pertains to scientific notation, a way to easily express really large or really small numbers.
You'll first notice that 10 has a negative exponent. This tells you that the number is going to be smaller than 10.
This is because 10^-3 translates to 1/10^3 based on exponent rules
With that, you know that your equation is 6.7/10^3
You can simplify that to:
[tex]\frac{6.7}{10^{3} }[/tex]
[tex]\frac{6.7}{1000}[/tex]
0.0067
In case you didn't know how I got there, 10^3 simply means 10 multiplied by itself 3 times.
The other method would be to look at your answer choices. Since we have a negative exponent, we can eliminate D.
Next, since we have a positive coefficient (6.7), we can eliminate A and B.
That leaves us with the answer C. 0.0067
