Which number is correctly expressed in scientific notation

1 Answer

Answer:

x*10ⁿ (units)

Step-by-step explanation:

Scientific notation never has leading or trailing zeros.

0.0064 would be expressed as 6.4*10³

6400 would be expressed as 6.4*10³

multiplying by 10 to an exponent just adds or subtracts zeros, so count how many zeros have to be added or subtracted, and multiply by 10ⁿ, where n is how far from the decimal point.
