Explanation opens after your attempt
Explanation
Simple Explanation
\(44^2=(40+4)^2=40^2+2\cdot40\cdot4+4^2=1600+320+16=1936\)। इसलिए सही उत्तर 1936 है। निकटतम भ्रामक विकल्प 1926 और 1946 असल में 10 से कम या अधिक हैं (गलत हैं) और 1956 20 अधिक है। परीक्षा टिप: 2-आंक्यताओं के वर्ग के लिए \((a+b)^2\) सूत्र का उपयोग करके तेज़ी से गणना करें या 1–50 तक के वर्ग याद रखें। / \(44^2=(40+4)^2=40^2+2\cdot40\cdot4+4^2=1600+320+16=1936\). Hence the correct value is 1936. The nearest distractors 1926 and 1946 are off by 10, while 1956 is off by 20, so they are incorrect. Exam tip: use the \((a+b)^2\) expansion for quick mental squaring of two-digit numbers or memorize squares up to 50.

Explanation
Simple Explanation
पहले घन निकालने के लिए घन का अर्थ है एक संख्या को तीन बार गुणा करना। \(35^2=35\times35=1225\)। अब \(35^3=1225\times35=(1225\times30)+(1225\times5)=36750+6125=42875\)। विकल्प C (42775) से फर्क सिर्फ 100 है — यह अक्सर गुणा के दौरान अधूरी जोड़ का सामान्य गणनात्मक त्रुटि है; इसलिए सही उत्तर 42875 है। परीक्षा टिप: बड़े अंकों का घन निकालते समय पहले स्क्वायर करें और फिर उस स्क्वायर को मूल संख्या से गुणा करें — इससे गणना आसान और कम त्रुटिपूर्ण होती है। / The cube means multiplying the number three times. First compute the square: \(35^2=35\times35=1225\). Then \(35^3=1225\times35=(1225\times30)+(1225\times5)=36750+6125=42875\). Option C (42775) is only 100 less — a typical arithmetic slip when adding partial products. Thus the correct value is 42875. Exam tip: compute the square first and then multiply by the base number to reduce mistakes in multi-digit multiplication.

462 = 46×46. इसे बाँटकर गुणा करने पर: 40×46 = 1840 और 6×46 = 276, इसलिए 1840+276 = 2116. विकल्प A और B केवल 10 का अंतर दिखाते हैं (2106 और 2126) — वे साधारण अंकगणना में हुई छोटी त्रुटियों के समान हैं। परीक्षा-सुझाव: वर्ग निकालते समय संख्याओं को 40+6 के रूप में विभाजित करके गुणा करें ताकि गलतियाँ कम हों। / 462 = 46×46. Break the multiplication: 40×46 = 1840 and 6×46 = 276, so 1840+276 = 2116. Options A and B differ by ±10 (2106 and 2126) and represent common small arithmetic mistakes.

समान आधार वाले घातों के गुणा का नियम है कि घातों को जोड़ा जाता है। अतः \(6^1\times6^2=6^{1+2}=6^3=216\)। विकल्प A (36) गलत है — यह तभी मिलेगा जब घातों को गलत तरीके से गुणा कर दिया जाए: \(6^{1\times2}=6^2=36\)। परीक्षा टिप: गुणा में घात जोड़ें; भाग में घात घटाएँ। / For multiplication with the same base add the exponents. Thus \(6^1\times6^2=6^{1+2}=6^3=216\). Option A (36) is incorrect — it corresponds to the wrong operation of multiplying exponents: \(6^{1\times2}=6^2=36\).

पहला कदम: 38 का वर्ग निकालें: \(38\times38=1444\)। फिर इसे 38 से गुणा करें: \(1444\times38=1444\times(30+8)=43320+11552=54872\)। अतः सही उत्तर 54872 है। विकल्प C (55872) के साथ का अंतर 1000 का अतिरिक्त मान होने के कारण गलत है — यह साधारण अंकगणना में जगह या जोड़ने की भूल को दर्शाता है। परीक्षात्मक सुझाव: बड़े घातों में पहले संख्या का वर्ग निकालकर फिर मूल संख्या से गुणा करें; यह त्रुटि कम करता है। / Compute stepwise: first square 38: \(38\times38=1444\). Then multiply by 38: \(1444\times38=1444\times(30+8)=43320+11552=54872\). So 54872 is correct. Option C (55872) is wrong because it differs by 1000 — a typical arithmetic slip (adding/subtracting a power of ten). Exam tip: for cubes, calculate the square first and then multiply by the base to reduce mistakes.

Simple Explanation
घात के नियम के अनुसार यदि आधार समान हों तो घात जोड़े जाते हैं: \(a^{m}\times a^{n}=a^{m+n}\)। यहाँ आधार 10 है और घात 1 तथा 2 हैं, अतः \(10^{1}\times10^{2}=10^{1+2}=10^{3}=1000\)। विकल्प B (100) तब होता यदि कोई घातों को गुणा कर देता (या केवल \(10^2\) ले लेता)। विकल्प A और D आम गलतियाँ हैं और दोनों व्याकरणिक रूप से गलत परिणाम देते हैं। परीक्षा-सुझाव: पहले दोनों अभिव्यक्तियों को घात रूप में लिखकर आधार समान होने पर घात जोड़ें; त्वरित जाँच के लिए \(10\times100=1000\) करें। / Use the law of exponents: when bases are equal, add the exponents: \(a^{m}\times a^{n}=a^{m+n}\). Here base 10 with exponents 1 and 2 gives \(10^{1}\times10^{2}=10^{1+2}=10^{3}=1000\). Option B (100) would result from the mistake of multiplying or ignoring exponents (or taking only \(10^2\)). Options A and D are also incorrect and reflect common calculation errors. Exam tip: convert factors to powers of the same base and add exponents; a quick check: \(10\times100=1000\).
