Answer:
[tex]7.14\times10^{12}[/tex]
Step-by-step explanation:
Given the following question:
[tex]3.4\times10^4\times2.1\times10^8[/tex]
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.
[tex]3.4\times10^4\times2.1\times10^8[/tex]
[tex]3.4\times10^4[/tex]
[tex]3.4\times10^4=3.4.0.0.0.=34000[/tex]
[tex]2.1\times10^8=2.1.0.0.0.0.0.0.0.=210000000[/tex]
[tex]34000\times210000000[/tex]
[tex]34000\times210000000=7140000000000[/tex]
[tex]7140000000000=7.14\times10^{12}[/tex]
[tex]7.14\times10^{12}[/tex]
Hope this helps.
