Question

Which shows 0.00234 written in scientific notation?

Answer 1

It’s D


the reason why is because the multiplier must be between 1 and 10
(
1
≤
x
≤
10
)
so first more your decimal there which you get:
2.34
then just count how many numbers the decimal jumped, if the decimal moved left the exponent is positive and if it moved right, as in your number, the exponent is negative

yours moved 3
