Question 1008515


{{{(5x/(48y^2)) + (7y/(18x^2y))}}}

{{{(5x/(48y^2)) + (7cross(y)/(18x^2cross(y)))}}}

{{{(5x/(48y^2)) + (7/(18x^2))}}}

{{{(5x/(48y^2)) + (7/(18x^2))}}}..........least common denominator is {{{144x^2y^2}}}

{{{((5x*3x^2)/144x^2y^2) + ((7y*8y^2)/(144x^2y^2))}}}


{{{(5x*3x^2 + 7y*8y^2)/(144x^2y^2))}}}


{{{(15x^3 + 56y^3)/(144x^2y^2))}}}
