The handwritten text in the image seems to be a mathematical expression, though it's a bit unclear due to the angle. From what I can see, the expression could be interpreted as:

$\sqrt{a + 6} + e^{x} = \ln(9 + x^3)$

This appears to be a non-linear equation combining different mathematical functions: square roots, exponential functions, and logarithms. Here’s a breakdown:

1. Square Root: $\sqrt{a + 6}$, where $a$ is some variable or constant.
2. Exponential: $e^x$, where $e$ is Euler’s number (approximately 2.71828), raised to the power of $x$.
3. Natural Logarithm: $\ln(9 + x^3)$, the natural logarithm of $9 + x^3$, where $x^3$ means $x$ cubed.

Would you like a detailed solution or explanation on how to solve this type of equation?

Here are 5 related questions:

1. What is the solution to this equation if specific values for $a$ and $x$ are given?
2. How do we differentiate this equation with respect to $x$?
3. How can we graph the functions involved in this equation?
4. What numerical methods can be used to solve such an equation?
5. How do exponential and logarithmic functions interact when solving equations?

Tip: Always check the domain of each function when working with logarithms and square roots. For example, $9 + x^3 > 0$ must hold for the logarithmic function.
