    3.876943x10^9

    7.317x10^-4

    Step-by-step explanation:

    3,876,943,000

    Put the decimal at the end

    3,876,943,000.

    Move it so only 1 number is before the decimal

    3.876943000

    We moved it 9 places, so that is the exponent

    We moved it to the left, so the exponent is positive

    The three zeros at the end can be dropped because they are the last numbers to the right of the decimal

    3.876943x10^9

    0.0007317

    Move it so only 1 number is before the decimal

    00007.317

    We moved it 4 places, so that is the exponent

    We moved it to the right, so the exponent is negative

    The four zeros at the left can be dropped because they are the last numbers to the left of the whole number

    7.317x10^-4
