Question

the mass of a textbook is approximately 0.00165 metric ton . how is this number written in scientific notation

Answer 1

1.65 X 10^-3 (i don't know if your teacher wants you to also add the unit at the end, but if your teacher does, then just add metric ton at the end. :-) )

Explanation:

We want to bring the decimal point to the right of the first number, so you move the decimal point 3 times to the right, which would give you 1.65 metric ton.

So you should know that moving a decimal point to the right would make the power negative, and moving the decimal point to the left would make the power positive.

In this situation, the power would be negative, and a negative three, because you moved the decimal point 3 times to the right.

Hope this helped :-) <3
