গাণিতিক সমস্যা: ৯/?=?/৮১
এখানে, প্রশ্নবোধক স্থানে একই সংখ্যা বসবে যা একটি গাণিতিক অনুপাত তৈরি করবে। 🤔
সমস্যার বিশ্লেষণ
আমরা জানি, অনুপাত:
- ৯ / x = x / ৮১
এখানে 'x' হলো সেই সংখ্যা যা আমাদের নির্ণয় করতে হবে। 🧐
সমাধানের ধাপ
- গুণন প্রক্রিয়া: ৯ * ৮১ = x * x
- ফল: ৭২৯ = x২
- বর্গমূল: x = √৭২৯
- উত্তর: x = ২৭ 🎉
ফলাফল
সুতরাং, প্রশ্নবোধক স্থানে ২৭ বসালে অনুপাতটি সঠিক হবে। 🥳
| প্রথম সংখ্যা | অনুপাত | দ্বিতীয় সংখ্যা |
|---|---|---|
| ৯ | : ২৭ | :: ২৭ |
| ২৭ | : ৮১ |
অতএব, সঠিক উত্তরটি হলো: ২৭। 💯
অন্যান্য তথ্য
- এটি একটি সমানুপাত এর উদাহরণ। 🤓
- সমানুপাত এর ক্ষেত্রে, প্রথম ও চতুর্থ পদের গুণফল দ্বিতীয় ও তৃতীয় পদের গুণফলের সমান হয়। 💡
আশা করি, এটি বোধগম্য হয়েছে! 😊
