Final answer:
The output of the C++ statement 'cout << pow(3.0, 2.0) + 5 << endl;' is 14, as it calculates 3.0 to the power of 2.0, which is 9.0, and then adds 5, resulting in a total of 14 with a new line at the end.
Step-by-step explanation:
The C++ statement cout << pow(3.0, 2.0) + 5 << endl; is used to calculate the power of a number and then output the result. The pow function raises the first argument to the power of the second argument, so pow(3.0, 2.0) calculates 3.0 squared (3.0 x 3.0), which results in 9.0. After calculating the power, 5 is added to that result, yielding 9.0 + 5 = 14.0. The output of this statement, therefore, is 14. The endl is a manipulator that inserts a new line character, so after the number 14, the cursor will move to the next line in the output console.
