Question$z = \ln(-10)$ Express in the form of $z = \ln a + bj$.

Studdy Solution
Express the logarithm in the form $z = \ln a + bj$. Using the formula for the logarithm of a complex number:
$$z = \ln |a| + i \arg(a)$$
Substitute the values:
$$z = \ln(10) + i\pi$$
Thus, the expression for $z$ is:
$$z = \ln(10) + \pi j$$
The expression for $z$ is:
$$\boxed{\ln(10) + \pi j}$$
