Question

factorise 16m⁵-144m³ using suitable identity
hint : identity used is
a²-b² = (a+b) (a-b)
answer is 16m³(m-3) (m+3)​

Answer 1

Answer:

16m³(m+3)(m–3)

Step-by-step explanation:

16 m³(m²–9). {taking 16 m³ common from 16m⁵-144m³

16m³(m²–3²). {9= 3²

16m³(m+3)(m–3). {by a²–b²= (a+b)(a–b)

Answer 2

Answer:

16m³(m+3)(m-3)

Step-by-step explanation:

• 16m³(m²-9) {taking 16 m³ as common}
• 16m³(m²-3²) {9 = 3²}
• 16m³(m+3)(m-3) Ans

By using identitie

a²-b²=(a+b)(a-b)
