Question

How would you put it in scientific notation 144,452,016 or 23,003,983?

Answer 1

1.44452016 X 10^8

2.3003983 X 10^7

Answer 2

For every place you move the decimal point to the left, add one to the power of 10, for every place you move to the right, subtract one.

So, 1,867,263 = 1.867263 * 10^6

and 0.00987 = 9.87 * 10^-3

Answer 3

The first number in scientific notation, called the coefficient, must be greater than or equal to 1 and less than 10. So the coefficient of 144,452,016 is 1.44452016 and the coefficient of 23,003,983 is 2.3003983. The power of ten is then decided by how many decimal spaces you moved in order to get that coefficient. If you moved the decimal place to the right, then the power is negative, and if you moved it to the left, the power is positive. In 144,452,016, the decimal was moved 8 places to the left, and in 23,003,983 the decimal was moved 7 places to the left. And that's all there is to it:

144,452,016 = 1.44452016 x 10^8

23,003,983 = 2.3003983 x 10^7
