You must include math.h to get the prototype for the
pow function. If you dont include math.h the compiler
believes that the function returns an int that then
gets converted to a double with dubious value.

#include <stdlib.h>
#include <math.h>

int main(int argc, char **argv)
{
   double result;
   result = pow (0.5, 0.75);
   printf ("The result is %f\n", result);
   return EXIT_SUCCESS;
}

C:\users\default>gcc -o pow.exe pow.c

C:\users\default>pow
The result is 0.594604
