求C语言高手编写程序：为实型变量X输入一个值后，输出X的值、X的平方根、X的平方、X的立方根和X的立方

#include <stdio.h>
#include <math.h>
main()
{
double x;
double v1,v2,v3,v4;
printf("Please input x:\n");
scanf("%lf",&x);
printf("Your input is: %g\n",x);
v1=sqrt(x);
v2=x*x;
v3= pow(x,1.0/3);
v4 = v2*x;
printf("The results are: %lf %lf %lf %lf\n",v1,v2,v3,v4);
return 0;

}
例如，输入8
得：The results are: 2.828427 64.000000 2.000000 512.000000本回答被提问者和网友采纳

math.h头文件中有相关数学函数的声明
#include <Math.h>后
在程序中使用相应的函数来做就行了。

#include "stdio.h"
#include "math.h"
main() {
int x,n;
int x1,x2,x3,x4;
printf("please entry a number \n");
scanf("%d",&x);
x1=x*x;
x2=sqrt(x);
n=1/3;
x3=pow(x,n);
x4=pow(x,3);
printf(" square is:%d\n square roots is:%d\n cube root is:%d\n cube is:%d",x1,x2,x3,x4);
putchar('\n');
}

下面都很详细了
