विशेष नोट : अगर आप जवाब ढूंढ लेते हैं तो ठीक, वरना कमेंट लिख दीजिएगा, मैं जवाब आपको मेल के जरिये भेज दूंगा...
क्या आप लोग मुझे बता सकते हैं, उत्तर का इकाई का अंक क्या होगा, यदि आप 7^46 (7 की घात 46) को हल करें...?
यदि इसी प्रश्न को मैं आसान भाषा में पूछूं, तो मुझे बताइए, शेषांक (शेषफल, अवशेष) क्या होगा, यदि 7^46 (7 की घात 46) को 10 से भाग कर दिया जाए...?
याद रखिए, कैलकुलेटर का प्रयोग न करें, तो बेहतर होगा, क्योंकि संभव है, वह आपको गलत जवाब दे...
और हां, अपने जवाब के पक्ष में तर्क भी दीजिएगा...
Now, the same riddle in English...
Special Note: If you succeed in solving this one, well and good; but in case, you don't, just leave a comment, and I will mail the answer to you...
Can you guys tell me, what would be the last digit (unit's), if you solve 7^46 (7 exponentiated by 46)...?
If I ask the same question in other words, what will the remainder be, if 7^46 is divided by 10...?
Please note that you should not use a calculator to solve this, as you may get a wrong answer...
Also, please do explain your answer...

ReplyDeleteJawaab dhoondhne ka tareeka bilkul sahi pakda hai aapne, lekin ek baar phir koshish keejiye, kyonki jawaab sahi nahin hai, Deepesh Bhai...
ReplyDeleteMaths background na hone ke karan thoda question samajhane me kathinai aa rahi hai fir bhi mere hisab se last digit of 7^46 will be 7.49 or 0.749048330965186
ReplyDeleteDear Anurag, ismein sharminda hone jaisi koi baat nahin hai... 7^46 ka arth hai, 7 ko 7 se ek ke baad ek 46 baar guna (multiply) karna... For example, 7^3 ka arth hota hai, 7 x 7 x 7 = 343...
ReplyDeleteSo, ab tak samajh hi gaye hoge, ki tumhaara jawaab sahi ho hi nahin sakta... Ab ek baar phir koshish karo... Best of luck, buddy...
7^46 solve karne par to ye aaya.... ab iska kya karu ?

Sahi nahin aaya Bhai... Yaar, itne saare zero kaise aa sakte hain, kisi bhi sankhya ko 7 se multiply karne par...?
ReplyDeletevivek bhai agar (7^23)*(7^23) kare to bhi answer vohi aata hai... ap aap hi kuch madad kariye.
ReplyDeleteJawaab tumhe mail kar deta hoon... Email ID bataao...
