Using algebraic identity $\frac{x^3 - y^3}{x^2 + xy + y^2} = x - y$:
For the first term, $x = 9.6$ and $y = 0.7$ (since $0.7^3 = 0.343$, $9.6 \times 0.7 = 6.72$, $0.7^2 = 0.49$):
For the second term, $x = 2.6$ and $y = 0.2$ (since $0.2^3 = 0.008$, $2.6 \times 0.2 = 0.52$, $0.2^2 = 0.04$):
$$\frac{(2.6)^3 - (0.2)^3}{(2.6)^2 + (2.6)(0.2) + (0.2)^2} = 2.6 - 0.2 = 2.4$$ $$\text{Total} = 8.9 + 2.4 = 11.3.$$बीजगणितीय सर्वसमिका $\frac{x^3 - y^3}{x^2 + xy + y^2} = x - y$ का उपयोग करने पर:
पहला पद: $x = 9.6, y = 0.7 \implies 9.6 - 0.7 = 8.9$
दूसरा पद: $x = 2.6, y = 0.2 \implies 2.6 - 0.2 = 2.4$
