- used to describe very large or very small numbers using powers of 10.
A few extra examples: 1. 4.5 X 10^3 = 4500
2. 6.9 X 10^6 = 6900000 3. 3.4 X 10^5= 340000
4. 8.4 X 10^9 = 8400000000 Convert from standard form to scientific notation: 1. 0.000000789 = 7.89 X 10^-8
2. 3400000 = 3.4 X 10^6
Convert from Scientific notation to standard form: 1. 6.4 X 10^8 = 640000000
2. 7.3 X 10^4 = 73000
To convert, from Scientific notation to standard form, in a calculator: 6.4 (EXP) 8
or 6.4 (EE) 8
6.4 (x10^)8
A problem to do, with your calculator: 1. (8 X 10^-6) - (4 X 10^-8) = 7.96 X 10^-6
2. (3.28 X 10^-5) X (5.47 X 10^9) = 1.7942 X 10^5

-Convert: 4.3 dm^2 to Gm
dm -> m -> Gm
10^2 dm^2=1m^2
10^18 m^2=1Gm^2
