Help please! Everett measured the weight of a substance as 0.000925 pounds. Which of the following shows the weight expressed in scientific notation?
a
0.925 x 10-3

b
9.29 x 104

c
9.25 x 10-5

d
9.25 x 10-4

Scientific notation is always between 1-10 times 10 to the power of how many decimal points it needs to be moved over

So the first number would be 9.25*10^-4. You can figure out the power by just moving the decimal over and count until the number is between 1 and 10
