Question

Write each number in scientific notation 730,000 and 0.00000104

Answer 1

Scientific notation wants you to use a number between 1 and 10, and multiply it by 10 to the power of something.

For the first one, the number we will take will be 7.3. The power by which you multiply it will be the number of places between the decimal point in 7.3, and the end of the number 730000.

You have to do the same for 0.00000104, but with a negative power that will bring you from the decimal point in 1.04 to the decimal point before the 5 zeros.

Answer 2

To write a number in scientific notation:

Put the decimal after the first digit and drop the zeroes.

In the number 123,000,000,000 The coefficient will be 1.23

To find the exponent count the number of places from the decimal to the end of the number.

In 123,000,000,000 there are 11 places. Therefore we write 123,000,000,000 as:
\[1.23\times10^{11}\]
