Explanation:

Given : Expression
`1217+(4.1* 10^3)`

To find : After converting the following numbers into scientific notation, solve the problem ?

Solution :

Expression
`1217+(4.1* 10^3)`

Re-write 1217 by multiplying and divide by 1000 to convert into decimal,

`=(1217* 1000)/(1000)+(4.1* 10^3)`

`=1.217* 10^3+(4.1* 10^3)`

`=(1.217+4.1)* 10^3`

`=5.317* 10^3`

Therefore, in scientific notation
`1217+(4.1* 10^3)=5.317* 10^3`
