Question

Can someone explain scientific notations and exponents? like how to do them

8th grade math!

Answer 1

Scientific Notation :

Example :


`4.5 * {10}^(3)`

The exponent is 3 in this case and is positive meaning the zeros will follow after the 5 in 4.5 and not before that like this,


`45000`

If it was negative then the zeros would follow before the 4 in 4.5 like this,


`0.0045`


`4.5 * {10}^(3)`

The picture shows how it is done!!

Just do the loops around the number and put and egg inside of it like a cup.

That's all!!

-------------------------------------------------

Exponents :


`{9}^(2)`

Or 9^2 is titled 9 to the power of 2.

You do NOT do this...


`9 * 2`

You do,


`9 * 9`

And if to the power of 5 then it'll be,


`9 * 9 * 9 * 9 * 9`

That's all!!

I hope that helps you out!! Any more questions, please feel free to ask me!!
