Question

a/b +b/a = 1 হলে a³+b³ এর মান কত​

Answer 1

Step-by-step explanation:

$\huge\boxed{\fcolorbox{black}{pink}{Answer}}$

$\boxed{\bf{\pink{\bigstar Given \longrightarrow}}}$

a / b + b / a = 1

$\boxed{\bf{\pink{\bigstar Find \longrightarrow}}}$

=> a ^3 + b^3

$\boxed{\bf{\pink{\bigstar Solution \longrightarrow}}}$

Let a = 1 and b = 0

=> a/b + b/a = 1

=> 1 = 1 [ Equation satisfied]

So,

=> a ^3 + b ^3

=> 1

Answer 2

Answer:

a/b +b/a =1

=>a²+b²/ab =1

=>a²+b² =ab

=>a²+b²-ab =0

এবার,

a³+b³

= (a+b)(a²-ab+b²)

= (a+b) ×0

= 0 (Answer)
