    I divided 1.4 x 10^9/3.0 x10^5=
    4.7 x 10^4 sec

    Try again. You got the exponent wrong

  • Algebra 2 -

    answer=4.7 x10^3

  • Algebra 2 -

    I thought you take 10^9-5 or 10^4 is the exponent

  • Algebra 2 -

    0.47*10^4 = 4.7*10^3

    I understand now. When i divided it gave me .047. Thank you for your help.
