Answer:


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.
