সরলীকরণ করুন: ((44)2 x (1)/(642))2 + 10

ধারণা:

সূচকের নিয়ম এবং সরলীকরণ

ব্যবহৃত সূত্র:

(am)n = amxn

am / an = am-n

গণনা:

আমাদের কাছে আছে,

⇒ ((44)2 x (1)/(642))2 + 10

প্রথমে, বন্ধনীর ভেতরে সরলীকরণ করুন:

⇒ (44x2 x (1)/(642))2 + 10

⇒ (48 x (1)/(642))2 + 10

যেহেতু 64 = 43, আমরা লিখতে পারি:

⇒ (48 x 1/(43x2))2 + 10

⇒ (48 x 1/(46))2 + 10

⇒ (48-6)2 + 10

⇒ (42)2 + 10

⇒ 42x2 + 10

⇒ 44 + 10

44 গণনা করুন:

⇒ 256 + 10

⇒ 266

∴ সঠিক উত্তরটি হল বিকল্প 4.
