Question

if 5m - 13n = 3m - 8n then find the value of 2m² + 13n²/2m² - 13n²​

Answer 1

Answer:

Answer is -1

Step-by-step explanation:

⇒5m-3m -13n= -8n

⇒2m - 13 n = - 8 n

⇒2m = 5n

⇒m = 5n/2

⇒n = 2/5m

hence we can write,

2m² + 13 n²/ 2m²- 13 n²

so, 25n²/2 + 13×4/25 m² / 25n²/2 - 13×4/25m²

= -1 ans.
