निम्नलिखित का मान क्या है: \(9^2 + 4^3\)?

What is the value of \(9^2 + 4^3\)?

Explanation opens after your attempt
Correct Answer

C. 145

Explanation

Simple Explanation

पहले घातांक का मूल्य निकालें: \(9^2=81\) और \(4^3=64\)। फिर जोड़ने पर \(81+64=145\) मिलता है, इसलिए सही उत्तर 145 है। विकल्प A (93) आम भूल दर्शाता है जहाँ \(4^3\) को \(4\times3=12\) समझ लिया जाता है। परीक्षा टिप: पहले एक्स्पोनेंट्स (घातांक) हल करें, उसके बाद जोड़ या अन्य क्रियाएँ करें। / Compute the powers first: \(9^2=81\) and \(4^3=64\). Adding these gives \(81+64=145\), so 145 is correct. Option A (93) is a common mistake from treating \(4^3\) as \(4\times3=12\). Exam tip: always evaluate exponents before performing addition or other operations.

निम्नलिखित का मान क्या है: \(16^2+17^2\)?

What is the value of \(16^2+17^2\)?

Explanation opens after your attempt
Correct Answer

C. 545

Explanation

Simple Explanation

सीधा तरीके से दोनों वर्ग निकालें: \(16^2=256\) और \(17^2=289\)। इन्हें जोड़ने पर \(256+289=545\) मिलता है। वैकल्पिक रूप से पहचान का उपयोग कर जांचें: \((16+17)^2-2\cdot16\cdot17=33^2-544=1089-544=545\)। निकटभ्रमी विकल्प \(535\) या \(555\) सामान्य अंकगणितीय त्रुटियों से आते हैं (जोड़/घटाना गलत करना)। परीक्षा सुझाव: बड़े वर्गों को याद रखें और पुष्टि के लिए \((a+b)^2-2ab\) पहचान से जल्दी जाँच करें। / Compute each square: \(16^2=256\) and \(17^2=289\). Adding gives \(256+289=545\). As a quick check use the identity \((a+b)^2-2ab\): \((16+17)^2-2\cdot16\cdot17=33^2-544=1089-544=545\). Close options like 535 or 555 result from simple addition/subtraction mistakes. Exam tip: memorize small squares and use the identity \((a+b)^2-2ab\) to verify sums of squares quickly.

\((22^2 + 32)\) का मान क्या है?

What is the value of \((22^2 + 32)\)?

Explanation opens after your attempt
Correct Answer

C. 516

Explanation

Simple Explanation

घात पहले निकालें: \(22^2 = 484\). फिर जोड़ें: \(484 + 32 = 516\)। इसलिए सही उत्तर 516 है। निकटतम भ्रामक विकल्प (506, 526, 496) इस गणना से मेल नहीं खाते — उदाहरण के लिये 506 तब होगा यदि गलती से 10 घटा दिया जाए। परीक्षा-सुझाव: किसी संख्या का वर्ग तेज़ी से निकालने के लिए विभाजन विधि इस्तेमाल करें, जैसे \((20+2)^2 = 20^2 + 2\times20\times2 + 2^2\)。 / Evaluate the exponent first: \(22^2 = 484\). Then add: \(484 + 32 = 516\). Thus the correct value is 516. The distractors (506, 526, 496) do not match this sum — for example 506 would result from subtracting 10 by mistake. Exam tip: compute squares quickly using expansion, e.g. \((20+2)^2 = 20^2 + 2\times20\times2 + 2^2\).
