Answer:

q = 0.3423122683

Step-by-step explanation:

We can find the exact solution to the exponential equation using the following steps:

Step 1:  Divide both sides by 26:

[tex](19=26(0.4)^{q})/26\\ \\19/26=0.4^q[/tex]

Step 2:  Take the log of both sides:

[tex]log(19/26)=log(0.4^q)[/tex]

Step 3:  Apply the power rule of logs to bring down q:

[tex]log(19/26)=q*log(0.4)[/tex]

Step 4:  Divide both sides by log(0.4) to solve for q:

[tex]\frac{log(19/26)}{log(0.4)}=q\\ \\0.3423122683=q[/tex]

Therefore, the exact solution to the equation is q = 0.3423122683.
