    Question Fourth root program. Help plese?

    Hello,
    i am to write a table of square roots and forthr roots like see:

    Integer Square root forth root

    1 1.00000000 1.00000000
    2 1.414213562 1.189207115
    3 1.732050808 1.1316074013
    4 2.000000000 1.414213562

    Now! I am good so far with the square root but my forth root is not coming out right. It reads 2.65 something or another and i need some help please.


    #include<stdio.h>
    #include<math.h>

    void prn_heading (void);
    void prn_and_read_data (void);

    int main()
    {
    prn_heading();
    prn_and_read_data();
    return 0;
    }

    void prn_heading(void)
    {
    printf("%3s%28s%28s%28s",
    "Integer", "Square Root", "Fourth Root\n",
    "--------------------------------------------------------------\n\n");
    return;
    }

    void prn_and_read_data (void)
    {
    int x;
    double square_root, fourth_root;

    for (x = 1; x <= 100; ++x)
    printf("%5d:%28.9e %28.9e\n", x = x, sqrt(x), square_root = pow(x, x));
    fourth_root = square_root * square_root;
    printf("%50.9e", fourth_root);
    ;
    return;
    }

    hm.....try using the pow() function for the fourth root. I'm not familiar with the function, but maybe that would work better. Why did you double-post instead of continuing on the last one? Most people don't like it when you do that.

    thats probably the closest your gonna get using the standard library functions, i dont know of any power function that will take double for an exponent

    Mr clown pimp, pimp, dog, sir

    Hello,
    Thanks for your help Mr. Clown Pimp!
    Is there anyway to write it though to produce the same results... say using exponents
    eg; say prints for int 2, 1.414213562e+00
    I am curious since this program has really gotten me stumped here but thanks for your gracious knowledge.
    later big pimppy!
