Question

plzzzzzzzz solve this​

Answer 1

Answer:

Step-by-step explanation:

We know that ,

If a + b + c = 0 ,then

a³ + b³ + c³ = 3abc

Here ,

a = 2r - 3s ,

b = 3s - 5t ,

c = 5t - 2r ,

Now ,

a + b + c = 2r - 3s + 3s - 5t +  5t - 2r  = 0

Therefore ,

(2r-3s)³+(3s-5t)³+(5t-2r)³

= 3abc

= 3(2r-3s)(3s-5t)(5t-2r)
