What is the value of (10^3-400)?(10^3-400) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 600600
Here, \(10^3 = 10 \times 10 \times 10 = 1000\). Therefore, \(1000 - 400 = 600\), so option D is correct. The value 700 would result from subtracting only 300 from 1000. Exam tip: evaluate the exponent first, then perform addition or subtraction.यहाँ \(10^3 = 10 \times 10 \times 10 = 1000\) है। इसलिए \(1000 - 400 = 600\), अतः सही विकल्प D है। 700 तब मिलता यदि 1000 में से केवल 300 घटाया जाता। परीक्षा टिप: घात का मान पहले निकालें, फिर जोड़ या घटाव करें।
