Answer 2

`2*10^8`

Explanation:

Given is a fraction of the form

`(9x10^9)/(4.5x10^1)`

Both terms are in scientific notation.

For easy simplification let us consider the number without powers of 10 separately and next powers of 10 terms separately

Simplify one by one to its simplest

i.e. take 9 and 4.5 first

`(9)/(4.5) =2\\(10^9)/(10^1)=10^(9-1)\\  =10^8`

Put to gether the answer as

`2*10^8`
