Answer 2

Answer:

$\rm Taking \ LCM,\\\\\\\dfrac{ax \times a}{b \times a}-\dfrac{by \times b}{a \times b}=a+b \\\\\\\dfrac{a^{2}x}{ab}-\dfrac{b^{2}y}{ab}=a+b \\\\\\ \dfrac{a^{2}x-b^{2}y}{ab}=a+b \\\\\\On \ Cross \ Multiplication \\\\\\We \ get, \\\\\\a^{2}x-b^{2}y=ab(a+b)\\\\\\a^{2}x-b^{2}y=a^{b}+b^{a}$
