Question

Simplify the expression shown below: ln(e^3/x^4)

a. 3-x^4
b. 3-4ln(x)
c. 3/x^4
d. 3e/4

Answer 1

ln(e^3/x^4) you can rewrite as
ln(e^3)-ln(x^4)
since ln have base e , ln(e^3)=3
ln(x^4) you can rewrite as 4ln(x)
formulas :
ln(a/b)=ln(a)-ln(b)
ln(a^n)=nln(a)

Answer 2

so 'B' ?

Answer 3

yup

Answer 4

awesome thanks man

Answer 5

no problem :)
