The diameter of a water molecule is about 0.0000003 millimeters, which can
be written as 3 x 10 millimeters. What is n?

Respuesta :

Answer:

3  ×  10  −  7 (-7 should be in upper top after 10)

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  

10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Hope this helps.
