यदि \(r=10^{2}\cdot10^{-5}\cdot10^{4}\), तो (r) का मान क्या है?
If \(r=10^{2}\cdot10^{-5}\cdot10^{4}\), what is the value of (r)?
Explanation opens after your attempt
A. (10)
Concept
For the same base (10), the exponent is (2-5+4=1), so \(r=10^{1}=10\). In exams, add exponents during multiplication.
Why this answer is correct
The correct answer is A. (10). For the same base (10), the exponent is (2-5+4=1), so \(r=10^{1}=10\). In exams, add exponents during multiplication.
Exam Tip
समान आधार (10) की घातें (2-5+4=1) हैं, इसलिए \(r=10^{1}=10\)। परीक्षा में गुणा में घातों को जोड़ें।
