Answers

Answer:

1.332 × 10-3

Step-by-step explanation:

you move the decimal point to the right until there's only one digit on the left side of it. the exponent is 3 because that's the number of places you moved the decimal point, and it's negative because you moved it to the right. if you move the decimal to the left it is positive, to the right is negative :)

By basic calculation We can represent 0.001332 in scientific notation as [tex]1.332\times 10^{-3}[/tex]

What is scientific notation?

Scientific notation is a way of expressing numbers big numbers in short form with approximate values.

Given number is 0.001332

we can write 0.001332 as

1332/1000000

or we can write it as

1.332/1000

and now we can write it in Scientific notation form as
