    No!!!!! You can't forget to write out the 10.

    28000000 = 2.8 \times 10^7

    Mathematically speaking, 2.8^7 = 2.8 \times 2.8 \times 2.8 \times 2.8 \times 2.8 \times 2.8 \times 2.8 \times 2.8 = 1349.2928512

    Power sign

    Generally ^ is the power sign in computer languages as many comupter languages can't display power properly.

    So 10^6 generally means 10*10*10*10*10*10 (6-times) or 1000000
