Final answer:
The solution of the given expression is 3 * (x+8)^(1/4) - 4.
Step-by-step explanation:
The question is asking for the solution of the expression: 3 * sqrt(sqrt(x+8)) - 4.
To solve this, we need to simplify the expression first. The inner square root, sqrt(x+8), cannot be simplified further. However, we can simplify the outer square root, sqrt(sqrt(x+8)), by replacing it with (x+8)^(1/4).
So, the given expression simplifies to 3 * (x+8)^(1/4) - 4. This cannot be simplified further, but it gives you the solution of the expression.
