Could anyone pls help me?? Thank you!!!
How can I solve the Logarithm : In(1/x) = 10 ???
Natural log is log base e, so ln(x) = 10 means that x is e raised to the 10th power.
Here ln(1/x) = 10, so 1/x = e10.
Now simple algebra will suffice:
x = 1/e10 = e-10
The definition of a logarithm will lead you to the solution.
If b is the base of the logarithm, then:
blogb(a) = a
e is the base for natural logarithms, so
eln(1/x) = 1/x
Then, since we know that ln(1/x) is 10,
eln(1/x) = e10 = 1/x
1/x = e10
x = 1/e10
x = e-10
