A n s w e r :
(7m - 8n)2 - (7m + 8n)2 =
(7m-8n) (7m-8n) +(7m+8n) (7m+8n)
[(7m)2 - 2(7m)(8n) + (8n)2] + [(7m)2 + 2(7m)(8n) + (8n)2]
= [49m2 - 112mn + 64n2]+ [49m2 + 112mn + 64n2
= (49 + 49)m2 + (112 - 112) mn + (64 + 64)n2
= 98m2 + 0(mn) + 128n2
= 98m2 + 128n2

जीवन की बुनियादी आर्थिक गतिविधियाँ वस्तुओं और सेवाओं का उत्पादन, वितरण और वितरण हैं। एक समाज को इन गतिविधियों की पूर्ति के दौरान संसाधनों की कमी का सामना करना पड़ेगा।
जैसा कि सीमित संसाधनों की उपलब्धता के कारण इस तरह की कमी स्पष्ट है, और मानवीय आवश्यकताओं की कोई सीमा नहीं है। इसलिए, आपूर्ति और मांग के बीच यह भिन्नता एक अर्थव्यवस्था की केंद्रीय समस्याओं के गठन की ओर ले जाती है।
अर्थव्यवस्था की केंद्रीय समस्याएं इन कारकों के इर्द-गिर्द घूमती हैं।
क्या उत्पादन करना है?
उत्पादन कैसे करें?
किसके लिए उत्पादन करें?
आइए इन बिंदुओं पर विस्तार से चर्चा करें।
1. क्या उत्पादन करने के लिए?
यह एक अर्थव्यवस्था में उत्पन्न होने वाली केंद्रीय समस्याओं में से एक है। यह उन वस्तुओं और सेवाओं के प्रकार से संबंधित है जिनका उत्पादन और उत्पादन की जाने वाली मात्रा की आवश्यकता होती है।
चूंकि संसाधन सीमित मात्रा में हैं, एक का अधिक उत्पादन करने से दूसरे का उत्पादन कम होगा।
2. उत्पादन कैसे करें?
यह पहलू उस प्रक्रिया या तकनीक से संबंधित है जिसके द्वारा वस्तुओं और सेवाओं का उत्पादन किया जा सकता है। आम तौर पर, ऐसी दो तकनीकें हैं जिनका उपयोग उत्पादन के लिए किया जा सकता है, जो हैं:
श्रम गहन तकनीक
राजधानी गहन तकनीक
उत्पादन के लिए तकनीक का चुनाव उस राष्ट्र में संसाधन की उपलब्धता पर निर्भर करता है, और इसलिए संसाधन आवंटन एक चुनौती बन जाता है।
3. किसके लिए उत्पादन करें?
यह समस्या उन लोगों को निर्धारित करने से संबंधित है जो उत्पादित वस्तुओं के अंतिम उपभोक्ता होंगे। चूंकि अर्थव्यवस्था में संसाधन दुर्लभ हैं, इसलिए समाज के सभी वर्गों को पूरा करना मुश्किल हो जाता है।
यह एक अर्थव्यवस्था में पसंद की समस्या के निर्माण की ओर जाता है एक अच्छा जो एक वर्ग के बीच की मांग में हो सकता है, समाज के दूसरे वर्ग के लिए मांग में नहीं हो सकता है।
आबादी के बीच आय वितरण में अंतर के कारण ऐसी स्थिति पैदा होती है, जो खरीद व्यवहार में बदलाव का कारण बनती है।

The graphical representation of 2x+ y= 6 is given in the figure below.
This line divides the xy-plane in two half planes, I and II.
Select a point (not on the line), which lies in one of the half planes, to determine whether the point satisfies the given inequality or not.
We select the point as (0, 0).
It is observed that,
2(0) + 0 ≥ 6 or 0 ≥ 6, which is false.
Therefore, half plane I is not the solution region of the given inequality.
Also, it is evident that any point on the line satisfies the given inequality.
Thus, the solution region of the given inequality is the shaded half plane II including the points on the line.
This can be represented as follows.

Given R = 5% per annum ,n = 3 years, Amount = 9261 rupees.
We know that A = P(1 + r/100)^n
9261 = P(1 + 5/100)^3
9261 = P(21/20)^3
P = 9261 * 20/21 * 20/21 * 20/21
= 9261 * 20 * 20 * 20/21 * 21 * 21
= 9261 * 8000/9261
= 8000.
Therefore the sum of money = 8000 rupees.

The Earth contains five major wind zones: polar easterlies, westerlies, horse latitudes, trade winds, and the doldrums. Polar easterlies are dry, cold prevailing winds that blow from the east. They emanate from the polar highs, areas of high pressure around the North and South Poles. There are three circulation cells: the Hadley cell nearest the equator, the Ferrel cell in the mid-latitudes, and the polar cell. There are three prevailing wind belts associated with these cells: the trade winds, the prevailing westerlies, and the polar easterlies.

One can notice that Sam's letter to Charley is engulfed with series of mysteries. When Charley was fussing with his stamp-collection in the night, he comes across an envelope among his oldest first day covers. In a way it should not have been there, but it was there. He had not seen that envelope before. It was there because someone had mailed it to his grandfather at his home in Galesburg, Illinois and it had been there since July 18, 1894. The post-mark revealed that the stamp was a six-cent with a picture at President Garfield.
Generally, the first day cover has only a blank paper in the envelope but there the paper was written and signed by Sam. It was only addressed to Charley. Sam had written that he had found the Third Level. It means that Charley was correct about the Third Level. Further he had been putting up at Galesburg, Illinois for two weeks where people had been enjoying a romantic life. He asked Charley and Louisa to go there. They should keep looking till they found the Third Level.
It is rather much astonishing how such a letter was never noticed earlier. It is all the more surprising how Sam disappeared and nobody knew his where abouts. But Charley had doubts about his (Sams) presence in Galesburg. It is also mysterious that the letter is written by Sam and is addressed to Charley on July 18, 1894. It is also strange to note that Sam is not else except Charley's psychiatrist.

Buddha tried to spread his message to the people by teaching in the ordinary language, Prakrit so that everybody could understand it. He travelled on foot, going from one place to another, teaching people. Also, he encouraged people to think for themselves rather than to simply accept what he said.
