I don't know about the unit though.
I'm assuming you're looking to find the expanded form of the number?
This number is in scientific notation. The easiest way to convert it to a normal number is to move the decimal place 14 to the right. I've attached a picture showing how to do this. You should get 630,000,000,000,000
There's a faster way to do this - notice that you need to move the decimal 14 to the right, and there's one number already after the decimal place. Therefore, 13 places will be filled with zeros. So, just write out 63 and add 13 zeros.

Hope that helps! Feel free to message me or leave a comment if I can clarify anything :)
The angle between the paths of John and Jake who were once facing each other comes to 58°.
What is the definition of angle between paths?
The angle between paths simply refers to sum of the angles of both paths should the line of the paths be extended indefinitely to the point where they both meet.
The problem above is envision as indicated in the attached image. Recall that they were both facing each other - thus creating an imaginary straight line.
Soon as they turned in different directions and walked in that direction, they created two different lines. Hence the total angle between them becomes the sum of the angles with which they turned. Which is
30 + 28 = 58°
