Answer:
[tex]1.92\times10^{-3}\operatorname{kg}[/tex]Explanation:
A number is said to be in standard/scientific form when it is expressed as a product of a number between 1 and 10 and a power of 10.
Given the number: 0.00192 kg
To write it in standard form, count the number of zeros before the first non-zero digit.
The number of zeros = 3
The negative of this is the required index
Therefore:
[tex]0.00192\operatorname{kg}=1.92\times10^{-3}\operatorname{kg}[/tex]
