Question

#Show that x/a = y/b​

Answer 1

Step-by-step explanation:

applying componendo dividendo on both

sides we get

a³+3a²b+3ab²+b³ x³+3x²y+3xy²+y³

_____________ = ___________

a³+3a²b-3ab²-b³ x³+3x²y-3xy²-y³

((a+b)/(a-b))³=((x+y)/(x-y))³

a+b/a-b=x+y/x-y it is in componendo divisendo form

so

a/b=x/y

x/a=y/b by re arrangement
