What is the simplified value of (\frac{13^{4}\cdot169^{-1}}{2197^{-1}})?(\frac{13^{4}\cdot169^{-1}}{2197^{-1}}) का सरल मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (13^{5})(13^{5})
Here (169^{-1}=13^{-2}) and (2197^{-1}=13^{-3}), so (\frac{13^{4}\cdot13^{-2}}{13^{-3}}=13^{5}). In exams, division by a negative power adds the exponent.(169^{-1}=13^{-2}) और (2197^{-1}=13^{-3}), इसलिए (\frac{13^{4}\cdot13^{-2}}{13^{-3}}=13^{5})। परीक्षा में ऋणात्मक घात से भाग करते समय घात जुड़ती है।
