Using the relation
ln(e<sup>x</sup> = x
For
e<sup>5x</sup> = 2
Take natural log on both sides,
ln(e<sup>5x</sup>) = ln(2)
5x = ln(2)
x = ln(2) / 5
Now make your pick for the answer.
ln(e<sup>x</sup> = x
For
e<sup>5x</sup> = 2
Take natural log on both sides,
ln(e<sup>5x</sup>) = ln(2)
5x = ln(2)
x = ln(2) / 5
Now make your pick for the answer.

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