b. in2/5
c. 5 in 2
d. in5/2

    typo those answers contain L's not I's

  • College Algebra - ,

    Using the relation
    ln(ex = x

    For
    e5x = 2
    Take natural log on both sides,
    ln(e5x) = ln(2)
    5x = ln(2)
    x = ln(2) / 5
    Now make your pick for the answer.

  • College Algebra - ,

    take the ln of both sides
    5x=ln2
    x= 1/5 ln2

    so, none of the choices are correct, unless on answer b you meant 1/5 ln2
