Answer:
[tex]\ln 0.4 \approx -0.92[/tex]
Step-by-step explanation:
Since x is lesser than 1, then value of its natural logarithm must be negative. Likewise, the natural logarithm is a transcendental function and an irrational number, then it can only be estimated by approximations. One approach is using Taylor Polynomials, whose approximation is:
[tex]\ln 0.4 \approx -0.92[/tex]
