\( k = \frac{\ln 2}{51570} \)
Solución
We start with the equation:
e^(–51570 k) = 1/2
Take the natural logarithm of both sides:
ln(e^(–51570 k)) = ln(1/2)
Using the property ln(e^x) = x, we get:
–51570 k = ln(1/2)
Recall that ln(1/2) = –ln2, so:
–51570 k = –ln2
Now divide both sides by –51570:
k = (–ln2)/(–51570)
Since the negatives cancel, the exact solution is:
k = ln2 / 51570

Simplifique esta solución Beyond the Answer
To solve the equation \( e^{-51570 k}=\frac{1}{2} \), we can start by taking the natural logarithm of both sides. This gives: \[ -51570 k = \ln\left(\frac{1}{2}\right) \] Next, we can isolate \( k \): \[ k = -\frac{\ln\left(\frac{1}{2}\right)}{51570} \] Using the property of logarithms \(\ln\left(\frac{1}{2}\right) = -\ln(2)\), we can rewrite \( k \): \[ k = \frac{\ln(2)}{51570} \] So the exact solution is: \[ k = \frac{\ln(2)}{51570} \]
