We can start by simplifying the expression inside the parentheses:
2√2^2 + 5 = 2(2) + 5 = 4 + 5 = 9
Now we substitute this back into the original expression:
3√64 + 3(2√2^2 + 5) = 3√64 + 3(9)
Since 64 is equal to 4^3, the cube root of 64 is 4:
3√64 + 3(9) = 3(4) + 3(9)
Now we can simplify further:
3(4) + 3(9) = 12 + 27 = 39
Therefore, the answer is not listed among the given options.
2√2^2 + 5 = 2(2) + 5 = 4 + 5 = 9
Now we substitute this back into the original expression:
3√64 + 3(2√2^2 + 5) = 3√64 + 3(9)
Since 64 is equal to 4^3, the cube root of 64 is 4:
3√64 + 3(9) = 3(4) + 3(9)
Now we can simplify further:
3(4) + 3(9) = 12 + 27 = 39
Therefore, the answer is not listed among the given options.

Oops! I apologize for the mistake.
Let's try again.
Recall that the cube root of 64 is 4 since 4^3 = 64.
Now, reevaluating the expression:
3√64 + 3(2√2^2 + 5)
= 3(4) + 3(2(2) + 5)
= 12 + 3(4 + 5)
= 12 + 3(9)
= 12 + 27
= 39
Therefore, the simplified expression is 39.
