please help me find the derivative

The image contains a handwritten mathematical function. The function is written as follows:

\[ g(a) = 8^{-\frac{a}{3}} \cdot \sin(5a) \]

This function defines \( g(a) \) in terms of the variable \( a \). It is composed of two main parts:

1. \( 8^{-\frac{a}{3}} \) - This represents an exponential function with base 8 raised to the power of \(-\frac{a}{3}\).
2. \( \sin(5a) \) - This represents the sine function, where the argument is \( 5a \).

To understand this function better:
- As \( a \) changes, \( 8^{-\frac{a}{3}} \) will exponentially decrease if \( a \) increases because of the negative exponent.
- The \( \sin(5a) \) function represents a periodic oscillation which remains bounded between -1 and 1, and oscillates more frequently due to the multiplication by 5.

Combining these, \( g(a) \) will exhibit an oscillatory behavior modulated by an exponentially decaying factor as \( a \) increases.
