Hi class!!! I don't know very weel what I have to do but I go to start.
Today in class we studied the Scientific Notation.
A number with a scientific notation has always two parts:
- A decimal number n verifying that _
- A power of 10 with an integer number as exponent.
For example: 300.000.000= 3·108
Then we have done some exercise about the scientific notation,that are: Page 42 (13-15)
13.a)493000000= 4'93·108 d)12'00056= 1'200056·10
b)315000000000= 3'15·1011 e)253=2'53·102
c)0'0004464= 4'464·10-4 f)256'256= 2'56256·102
red= important things
blue= the exponents
I think that that's all:))
I put some videos to entertainment:P
