Question 397532
I guess you have this:

{{{(8 x^7/ 7q^4)( 49q^7/ 64x)}}} ....... 



{{{((8x^7)(49q^7))/ ((7q^4)(64x))}}}


{{{((8x^cross(7)6)(49q^cross(7)3))/ ((7q^cross(4))(64cross(x)))}}}


{{{((cross(8)x^6)(cross(49)7q^3))/ (cross(7)cross(64)8)}}}


{{{((x^6)(7q^3))/ 8}}}


{{{((x^6)(7q^3))/ 8}}}




{{{(7q^3x^6)/ 8}}}
