Find the value of (a³ + b³) / (a² − ab + b²) when a = 157 and b = 143.
Solution
Correct Answer: Option D
আমরা জানি, a3 + b3 = (a + b)(a2 - ab + b2)
প্রদত্ত রাশি, (a3 + b3) / (a2 - ab + b2)
= {(a + b)(a2 - ab + b2)} / (a2 - ab + b2)
= (a + b)
এখন, a = 157 এবং b = 143 বসিয়ে পাই,
= 157 + 143
= 300
প্রদত্ত রাশি, (a3 + b3) / (a2 - ab + b2)
= {(a + b)(a2 - ab + b2)} / (a2 - ab + b2)
= (a + b)
এখন, a = 157 এবং b = 143 বসিয়ে পাই,
= 157 + 143
= 300
