Answer:
- None of these
Step-by-step explanation:
25a²b - b/25a² =
= 25a²b/1 - b/25a² =
= 25a²×25a²b/25a²×1 - b/25a² =
= 625a⁴b/25a² - b/25a² =
= 625a⁴b-b/25a²

Answer:
b(5a - 1/5a) (5a + 1/5a)
Step-by-step explanation:
- * 25a²b - b/25a²
taking b as common
= b(5a² - 1/5a²)
= b(5a - 1/5a)²
as, a² - b² = (a+b) (a-b)
therefore, b(5a - 1/5a) (5a + 1/5a)
