solve the above question​

Answer 1

Step-by-step explanation:

$\huge{ \pink{ \boxed{ \bold{ \green{Solution :- }}}}}$

$\large{ \underline{ \bold {\blue{Formula - }}}}$

$\bold{(x - y)³ = x³ - 3x²y + 3xy² - y³}$

$\bold{x = 4a \: \: , \: \: y = 5b}$

$\bold { \scriptsize{(4a - 5b)^{3} = ({4a})^{3} - 3({4a})^{2}(5b) + 3(4a) ({5b})^{2} - ({5b})^{3} }}$

$\bold{ \scriptsize{ = 64 {a}^{3} - 240 {a}^{2}b + 300a {b}^{2} - {125b}^{3} }}$
