For this case we have to:
By definition, the scientific notation is given by:
[tex]a * 10 ^ b[/tex]
Where:
a: It is a number greater than or equal to 1 and less than 10. It is called "mantissa".
b: It is the order of magnitude.
We have the following decimal number:
0.001742
Rewriting in scientific notation we have:
[tex]0.001742 = 1.742 * 10 ^{ -3}[/tex]
Answer:
[tex]1.742 * 10 ^{ -3}[/tex]
