Scientific notation, that is exponential this way of representing a real number, decimal. It is used, for example, scientific calculators, or in some computer programs.
9680 = 9 , 68 ∗ 1 0 3
There is here a form of writing in the form of a mantissa and exponent.
S c i e n t i f i c n o t a t i o n : a × 1 0 n w h ere a ∈ [ 1 ; 10 ) an d n ∈ Z
9680 = 9 ← 3 680 = 9.680 × 1 0 3 = 9.68 × 1 0 3
To express 9680 in scientific notation, write it as 9.68 times 10 raised to the power of 3. This is done by moving the decimal point three places to the left and ensuring one digit remains to the left of the decimal. Therefore, 9680 = 9.68 × 1 0 3 .
