    For this question, you first divide the leading coefficient (5.2) by 25 because it is the number thst holds the value other than just zeros.
    5.2/25 = .208
    Currebtly the have the answer .208 × 10^8
    In proper scientific notation, however, the leading coefficient must be between 1 and 9 (including those values). This means that the leading coefficient we have must be multiplied by 10. To do this, one exponential power is “moved” from the ten power to to the leading coefficient, resulting in the decrease of the power to 7 and the increase of the leading coefficient to 2.08. Every time a teb is removed from the power to be multipled against the leading coefficient, the power decreases by one.

    With this info, the final answer is
    2.08 × 10^7 or B
    I hope this helps!
