Question

how do i solve e^x+9=4

Answer 1

solve for x?

Answer 2

\[\ln4 -9=x\]

Answer 3

first subtract 9 from both sides, u get
e^x=-5
take log on both sides, u get
x ln e = ln(-5)
but since ln of negative number is not defined, this equation has 'no solution'.
understood this ?

Answer 4

@hartnn I actually think he might have meant \[e^{x+9} = 4\]

Answer 5

ohh!!
@sirena94 is it ?

Answer 6

yup, it is e^(x+9)=4
so ln4-9 is correct.

Answer 7

Alrighty! Thanks.
