Write the number 3940 in scientific notation

3.94 x 10^3

Step-by-step explanation:

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10^b

a = 3.94 (Please notice any zeroes on the end have been removed)

b = 3

Now the whole thing:

3.94 x 10^3

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
