If (r=10^{2}\cdot10^{-5}\cdot10^{4}), what is the value of (r)?यदि (r=10^{2}\cdot10^{-5}\cdot10^{4}), तो (r) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (10)(10)
For the same base (10), the exponent is (2-5+4=1), so (r=10^{1}=10). In exams, add exponents during multiplication.समान आधार (10) की घातें (2-5+4=1) हैं, इसलिए (r=10^{1}=10)। परीक्षा में गुणा में घातों को जोड़ें।
