answer in scientific notation.
(Round your answer to the nearest tenth.)

Answer 1

`7.14*10^(12)`

Explanation:

Given the following question:


`3.4*10^4*2.1*10^8`

In order to find the answer to this question we convert both scientific notations into standard form, multiply, and then convert back into scientific notation.


`3.4*10^4*2.1*10^8`

`3.4*10^4`

`3.4*10^4=3.4.0.0.0.=34000`

`2.1*10^8=2.1.0.0.0.0.0.0.0.=210000000`

`34000*210000000`

`34000*210000000=7140000000000`

`7140000000000=7.14*10^(12)`

`7.14*10^(12)`

Hope this helps.
