    scientific notation

    Here are a few examples of scientific notation. Let me know if it makes sense.
    1 * 10^{-1} = 0.1
    2 * 10^{-1} = 0.2
    2 * 10^{-3} = 0.002
    2 * 10^{3} = 200

    it should be 2\cdot10^3=\bold{2000}

    Hello, blame_canada100!

    First of all, release your CapsLock.
    All upper-case letters is impolite . . . it's shouting.


    How do you write numbers in scientific notation?

    A quantity in scientific notation is a number n,\;1 \leq n < 10, times a power of 10.


    Examples

    . . (a)\;238,000 = 2.38 \times 10^5

    . . (b)\;0.00057 \,= \,5.7 \times 10^{-4}


    In example (a), 238,000 was transformed to 2.38
    . . by moving the decimal point (far right) five places to the left.
    In effect, we have divided by 100,000
    . . so we multiply by 100,000 = 10^5

    In example (b),  0.00057 was transformed to 5.7
    . . by moving the decimal point four places to the right.
    In effect, we have multiplied by 10,000
    . . so we divide by 10,000 ... or multiply by \frac{1}{10,000} = 10^{-4}

    Yes. Consider the user warned. No shouting.

    Why did you revive a dead thread from a few months? The user is probably never going to view it.

    I saw a guest looking at it, and since I'm not a moderator I couldn't edit his post, so I just posted the correction. And then came Soroban...
