To find the value of \( A(8) \), we need to clarify the equation provided. It appears there is a small confusion in the equation you posted. The correct form for the exponential growth of the bug population that doubles every 4 days should be:
\[ A(t) = A_0 \cdot 2^{t/T} \]
where
- \( A_0 \) is the initial population,
- \( T \) is the period of doubling (4 days in this case),
- \( t \) is the time in days.
Given that the initial population \( A_0 \) is 6, the equation becomes:
\[ A(t) = 6 \cdot 2^{t/4} \]
Now, to find \( A(8) \):
\[ A(8) = 6 \cdot 2^{8/4} \]
Calculating the exponent:
\[ 8/4 = 2 \]
So we have:
\[ A(8) = 6 \cdot 2^2 \]
Calculating \( 2^2 \):
\[ 2^2 = 4 \]
Now, substituting back:
\[ A(8) = 6 \cdot 4 = 24 \]
Thus, the value for \( A(8) \) is \( \boxed{24} \).
