Question

Select the number that is equal to three times ten to the seventh power.

Answer

Three times ten to the seventh power can be written numerically as the following:

$3\times10^7$

When a number between one and ten is multiplied by a power of ten it is said to be written in scientific notation. This number is currently written in scientific notation.

Even though this appears to be a challenging math problem (i.e. because we have a power of ten), we can simply move our decimal place after the three, or , over spaces to the right using zeros as place holders.

$3.0\times 10^7=30000000.0$

Add commas and simplify.

$30000000.0\rightarrow30\textup,000\textup,000$

Compare your answer with the correct one above
