Question

See attached pic for problem. Has 2 parts- A and B

Answer 1

A) to find,

`(3.7*10^4)*(2.7*10^7)`

we know that,

`a^n* a^m=a^(n+m)`

we get,

`=3.7*10^4*2.7*10^7`
`=3.7*2.7*10^(4+7)`
`=9.99*10^(11)`

The scientific notation of the above result is,

`=9.99*10^(11)`

Answer is:

`=9.99*10^(11)`

B) To simplify,

`(45000000)/(5000)`
`=91000`

The scientific notation of the above result is,

`=9.1*10^4`

Answer is:

`9.1*10^4`
