question 25 plzz answer this one​

Answer 1

Answer:

Step-by-step explanation:Solution:-

a³ + b³ + c³ - 3abc = (a + b + c) (a² + b² + c² - ab - bc - ca)

Here,

a = l/m, b= m/n and c = n/l

Thus,

l³/m³ + m³/n³ + n³/l³ -3*l/m*m/n*n/l = [l/m + m/n +n/l][l²/m² + m²/n² + n²/l² - l/m*m/n - m/n*n/l - n/l*l/m

l³/m³ + m³/n³ + n³/l³ - 3 = [l/m + m/n + n/l][l²/m² + m²/n² + n²/l² - l/n - m/l - n/m]
