simplify e^(4ln(x))?

Question

i should know this. it is an easy problem i just cant think of the solution

Answer 1

x^4

Answer 2

x^4.

Answer 3

e^(4ln(x)) = e^(ln(x^4))

The e and ln cancel out, leaving you with

x^4 as the answer.

Answer 4

e^(4ln(x)) =e^(ln(x^4))=x^4

Answer 5

let assume
y = e ^ (4 ln(x))
ln y = ln ( e^ (4 ln(x))
ln y = 4 ln(x) . ln e
ln y = 4 ln(x)
ln y = ln (x^4)
y = x^4

Answer 6

=(e^(inx))^4
=x^4
