Question

Write your answer in scientific notation (2.5•10^8)•(2•10^3)

Answer 1

`5*10^(11)`

Explanation:

In order to get the answer to this question you will have to put the scientific notations into their number form then multiply, then change back into scientific notation form.

`(2.5*10^8)*(2*10^3)`

Turn the notations into their number form:

`2.5*10^8`

The exponent is positive so move the decimal point to the right:

`2.5*10^8=250000000`

Do the same with the second notation:

`2*10^3`

Since the exponent is positive move the decimal point to the right:

`2*10^3=2000`

Now multiply:

`250000000 * 2000 = 500000000000`

Now turn the number into scientific notation:

`500000000000 = 5.0*10^(11)`

`=5*10^(11)`

Hope this helps.
