`(5.7xx10^(6))div(4.2xx10^(3))" "(ii)(5.7xx10^(6))div(4.2xx10^(-3))" "(iii)(5.7xx10^(-6))div(4.2xx10^(-3))`

Text Solution

Verified by Experts

`(5.7xx10^(6))div(4.2xx10^(3))=(5.7xx10^(6))/(4.2xx10^(3))=(5.7)/(4.2)xx10^(6-3)=1.357xx10^(3)`
`(ii) (5.7xx10^(6))div(4.2xx10^(-3))=(5.7xx10^(6))/(4.2xx10^(-3))=(5.2xx10^(6))/(4.2xx10^(-3))=(5.7)/(4.2)xx10^(6-(-3))=1.357xx10^(9)`
`(iii)(5.7xx10^(-6))div(4.2xx10^(-3))=(5.7xx10^(-6))/(4.2xx10^(-3))=5.7xx10^(-6(-3))=1.357xx10^(-3)`
