Answer:

A) to find,

[tex](3.7\times10^4)\times(2.7\times10^7)[/tex]

we know that,

[tex]a^n\times a^m=a^{n+m}[/tex]

we get,

[tex]=3.7\times10^4\times2.7\times10^7[/tex][tex]=3.7\times2.7\times10^{4+7}[/tex][tex]=9.99\times10^{11}[/tex]

The scientific notation of the above result is,

[tex]=9.99\times10^{11}[/tex]

Answer is:

[tex]=9.99\times10^{11}[/tex]

B) To simplify,

[tex]\frac{45000000}{5000}[/tex][tex]=91000[/tex]

The scientific notation of the above result is,

[tex]=9.1\times10^4[/tex]

Answer is:

[tex]9.1\times10^4[/tex]
