Is 43.7 times 106 a scientific notation?

Answer 1

No. That is a multiplication problem. Here is the answer (4,632.2) written in scientific notation: 4.6*10^3 _____Because scientific notation is only an approximate answer (4.6 multiplied times 10 to the third power is 4,600) it is really only useful for really big numbers, or for your math or science class. To write a number in scientific notation you only have two digits of the number (the second digit is rounded according to the number proceeding it), then you add *10^_ (the blank being however many decimal points from a whole number it is). Here are a few examples:

.00236 = 2.4 *10^-3 (negative because you move the decimal to the right)

12,345,687 = 1.2 *10^7
