Could anyone pls help me?? Thank you!!!
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 = e^{10}.
Now simple algebra will suffice:
x = 1/e^{10} = e^{-10}

The definition of a logarithm will lead you to the solution.
If b is the base of the logarithm, then:
b^{logb(a)} = a
e is the base for natural logarithms, so
e^{ln(1/x)} = 1/x
Then, since we know that ln(1/x) is 10,
e^{ln(1/x) =} e^{10} = 1/x
1/x = e^{10}
x = 1/e^{10}
x = e^{-10}
