    Answer:

    2.23\times10^4

    Step-by-step explanation:

    In order to get the answer to this question you need to turn the scientific notations into standard form then subtract the two standard forms.

    (2.2\times10^{-4})-(3\times10^2)

    Turn the notations into standard form:

    2.2\times10^{-4} = .00022

    3\times10^2=300

    .00022-300=22300

    =22300

    Turn into notation form:

    22300 = 2.23\times10^{4}

    Hope this helps.
