Question

2.29 LAB: Using math functions Given three floating-point numbers x, y, and z, output x to the power of z, x to the power of (y to the power of 2), the absolute value of y, and the square root of (xy to the power of z). Output each floating-point value with two digits after the decimal point, which can be achieved as follows: printf("%0.2of", your Value); Ex: If the input is: 5.0 6.5 3.2 the output is: 172.47 340002948455826440449068892160.00 6.50 262.43

Answer 1

Answer:

The solution code is written in C++

1.    double x, y, z;  
2.    
3.    cout<<"Enter three number: ";
4.    cin>>x>>y>>z;
5.    
6.    printf("%0.2f\n", pow(x, z));
7.    printf("%0.2f\n", pow(x, pow(y, 2)));
8.    printf("%0.2f\n", abs(y));
9.    printf("%0.2f", sqrt(pow(x*y, z)));

Explanation:

Firstly, let's declare three variables x, y and z with double type (Line 1).

We prompt user for three floating point values and assign each of the input to x, y, z, respectively (Line 4).

Next, use printf() function to output the result based on the mathematical expression as required by questions. The "%0.2f" in printf() function enable us to output the floating-point value with two digits after the decimal point(Line 6-9).
