1.22 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("%0.21f", yourValue); Ex: If the input is: 5.0 6.5 3.2 the output is: 172.47 3400029484 40449068892160.00 6.50 262.43 LAB ACTIVITY 1.22.1: LAB: Using math functions 0/10 main.c Load default template... 1 #include <stdio.h> 2 3 int main(void) { 4 double x; 5 double y; 6 double z; 7 8 /* Type your code here.

Answer 1

Looking at your image I assume you have to use the math library that C provides.

First you need to import or include the library using #include<math.h>

Now the functions which you will require are:

1) Power Function : declaration -- double pow(double x, double y)

The pow function returns a double value corresponding to xy .

2) Absolute Value Function : declaration : int __cdecl abs ( int x)

Dont worry about the return type of the function it is an advanced C concept

3) Square Root Function : Declaration : double __cdecl sqrt(double _X);

Now here is the code :

#include<stdio.h> #include<math.h> int main(){ double x; double y; double z; scanf("%lf", &x); scanf("%1f", &y); scanf("%lf", &z); double xpowz pow(x,z); // This contains X^Z double xpowy2 = pow(x, pow(y,2)); // This contains X^(Y^2) double absy abs(y); // This contain |Y| double root sqrt(pow((x*y),z));// This contains the square root function printf("%0.21f ", xpowz); printf("%0.21f ", xpowy2); printf("%0.21f ', absy); printf("%0.21f ", root);| return 0; = 11 }

Now if you use a command line compiler instead of a online compiler you may need to add a extra term (-lm) in the compile command

Example command : gcc filename.c -lm

Answer 2

#include<stdio.h> #include<math.h> int main(){ double x; double y; double z; scanf("%lf", &x); scanf("%1f", &y); scanf("%lf", &z); double xpowz pow(x,z); // This contains X^Z double xpowy2 = pow(x, pow(y,2)); // This contains X^(Y^2) double absy abs(y); // This contain |Y| double root sqrt(pow((x*y),z));// This contains the square root function printf("%0.21f ", xpowz); printf("%0.21f ", xpowy2); printf("%0.21f ', absy); printf("%0.21f ", root);| return 0; = 11 }
