5.19.3.Use math function: sqrt, pow, log
#include <cmath>
#include <iostream>
using namespace std;

int main()
{
  double number, dsqrt,dpow,dlog;

  cout << "Please enter a number \n";
  cin >> number;

  dsqrt =sqrt(number);
  dpow =pow(number,5);
  dlog =log(number);

  cout << " Math Example\n";
  cout << " Square Root is " << dsqrt << "\n";
  cout << " Raised to the fifth power is " << dpow << "\n";
  cout << " Log is " << dlog << "\n";

  return 0;
}
Please enter a number
