Evaluate the following expression. Do not use a calculator.

[tex]\ln e^{\frac{3}{7}} = \square[/tex] (Type an integer or a fraction.)


Sagot :

To evaluate the expression [tex]\(\ln(e^{\frac{3}{7}})\)[/tex], we can use the properties of logarithms, specifically the natural logarithm. Here's the step-by-step process:

1. Recognize the property of the natural logarithm that we will use: [tex]\(\ln(e^x) = x\)[/tex]. This property states that the natural logarithm of [tex]\(e\)[/tex] raised to any power [tex]\(x\)[/tex] is simply [tex]\(x\)[/tex].

2. Identify the exponent in the expression given. In this case, the exponent is [tex]\(\frac{3}{7}\)[/tex].

3. Apply the property to simplify the expression:
[tex]\[ \ln(e^{\frac{3}{7}}) = \frac{3}{7} \][/tex]

Therefore, the value of the expression [tex]\(\ln(e^{\frac{3}{7}})\)[/tex] is [tex]\(\frac{3}{7}\)[/tex].

So, [tex]\(\ln(e^{\frac{3}{7}}) = \frac{3}{7}\)[/tex].

When expressed as a decimal, [tex]\(\frac{3}{7} \approx 0.42857142857142855\)[/tex].
