Okay! I missed like, 3 daus of school because of shots and stuff. But, we're doing scientific Notation and monomials/Polynomials! I don't understand them! The first question for scientific Notation is:
Write in Scientific Notation
1)4 500 000
2)o.089
3)0.2
4)0.000 055
I CANNOT GET THAT!
Then there is
45 x ten to the power of seven...
and 0.34 x ten to the power of six...
IT GOES ON!!
Then I have to write these in decimal form
2.3 x ten to the power of eight
HELP ME!

Re: Math
Well, the idea of scientific notation goes like this:
you know that 10^1 (10 to the power of one) = 10. 10^2 = 100. 10^3= 1000. 10^0 = 1, 10^-1 = 0.1, 10^-2 = 0.01, and so on.
The idea is, that in scientific notation instead of writing a number like it is you write it as a number between 1 and 10, times 10 to the power of what you need to get the original number.
Example: 20 = 2 x 10^1. Or 456 = 4,56 x 10^2.
So it should be:
1) 4.5 x 10^6
2) 8.9 x 10^-2
3) 2 x 10^-1
4) 5.5 x 10^-5
And so on.
