Question

plz help me in writin this answer in brief​

Answer 1

Step-by-step explanation:

64a^3/125 - 96a^2/25 + 48a/5 - 8

(4a/5)^3 - 3(4a/5)^2 (2) + 3(4a/5)(2)^2 - 2^3

using identity: a^3 - 3a^2b + 3ab^2 - b^3

= (a- b)^3

= (4a/5 - 2)^3 = (4a/5 - 2)(4a/5 - 2)(4a/5 -2)

Answer 2

Answer:

64a^3/125 - 96a^2/25 + 48a/5 - 8

(4a/5)^3 - 3(4a/5)^2 (2) + 3(4a/5)(2)^2 - 2^3

using identity: a^3 - 3a^2b + 3ab^2 - b^3

= (a- b)^3

= (4a/5 - 2)^3 = (4a/5 - 2)(4a/5 - 2)(4a/5 -2)
