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

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.

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
