You have to select math library in Library manager.

Upload the code where you've used "pow" - the code that shows the error.

The code that shows the error :

void main()
{
  int i;
  TRISB = 0;
  while(1)
  {
      PORTB = 1;
      Delay_ms(300);
      for (i = 0; i<=7; i++)
        {
          PORTB = pow(PORTB,2);
          Delay_ms(300);
        }
  }
}
