Question

44) Write the result after applying componendo and
dividendo to 3a²+2b²:3a²-2b²::3c²+2d²:3c²-2d².​

Answer 1

Step-by-step explanation:

apply companendo and dividendo rule

$\frac{3 {a}^{2} + 2 {b}^{2} }{3 {a}^{2} - 2 {b}^{2} } = \frac{3 {c}^{2} + 2 {d}^{2} }{3 {c}^{2} - 2 {d}^{2} }$

hence we know companendo and dividendo rule

$\frac{a}{b} = \frac{c}{d} \: \: then \: \frac{a - b}{a + b} = \frac{c - d}{c + d}$

use relations and do it
