    Answer:

    5\times10^{11}

    Step-by-step explanation:

    In order to get the answer to this question you will have to put the scientific notations into their number form then multiply, then change back into scientific notation form.

    (2.5\times10^8)\times(2\times10^3)

    Turn the notations into their number form:

    2.5\times10^8

    The exponent is positive so move the decimal point to the right:

    2.5\times10^8=250000000

    Do the same with the second notation:

    2\times10^3

    Since the exponent is positive move the decimal point to the right:

    2\times10^3=2000

    Now multiply:

    250000000 \times 2000 = 500000000000

    Now turn the number into scientific notation:

    500000000000 = 5.0\times10^{11}

    =5\times10^{11}

    Hope this helps.
