Question 1199929
<pre>
Find the product xy, where x and y are positive integers and {{{0=3x^4-x^3*y-9317}}}
                 {{{system(matrix(1,3, 0, "=", 3x^4 - x^3y - "9,317"), or, matrix(1,3, 3x^4 - x^3y, "=", "9,317"))}}}

                 {{{system(matrix(1,3, x^3(3x - y), "=", 7(11^3)), or, matrix(1,3, x^3(3x - y), "=", (11^3)7))}}} ---- Prime factors of 9,317: <b><font color = red><font size = 4>7(11<sup>3</sup></font></font></b>), or <b><font color = red><font size = 4>(11<sup>3</sup>)7</font></font></b>

                 {{{system(matrix(1,7, x^3, "=", 7, and, 3x - y, "=", 11^3), or, matrix(1,7, x^3, "=", 11^3, and, 3x - y, "=", 7))}}} ------ Equating terms on left and right sides

                      {{{matrix(1,3, x^3 <> 7, and, 3x - y <> 11^3)}}}, since x and y will NOT be INTEGERS, and it's stated that x and y are POSITIVE INTEGERS.

           Therefore, {{{matrix(1,3, x^3, "=", 11^3)}}} and so, <b><font color = red><font size = 4>x = 11</font></font></b> (EXPONENTS are equal and so are their BASES).
                           Also, {{{matrix(6,3, 3x - y, "=", 7, 3(11) - y, "=", 7, - y, "=", 7 - 33, - y, "=", - 26,  y, "=", (- 26)/(- 1), highlight(y), "=", highlight(26))}}}

                                  So, {{{highlight_green(matrix(1,5, xy, "=", 11(26), "=", 286))}}}</pre>
