Why do we use scientific notation, and what are the parts of an expression written in scientific notation?
kiruha [24]

Answer:

We use scientific notation as sometimes numbers are so so big, that it becomes inconvenient for us to write the actual number.

Step-by-step explanation:

For example, if you have 9 billion of something, you wouldn't want to write those 9 zeroes all the time.

When writing in scientific notation we count the number of decimal places to when we have one non-zero integer to the right of the decimal place. We then write that number and multiply it by ten to the number of decimal places you counted earlier.

e.g. 4.8 X 10^7
