What is the value of (\frac{3^{-2}+3^{-4}}{3^{-3}})?(\frac{3^{-2}+3^{-4}}{3^{-3}}) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\frac{10}{3})(\frac{10}{3})
Here (3^{-2}+3^{-4}=\frac{1}{9}+\frac{1}{81}=\frac{10}{81}), and (3^{-3}=\frac{1}{27}). Division gives (\frac{10}{3}).(3^{-2}+3^{-4}=\frac{1}{9}+\frac{1}{81}=\frac{10}{81}) और (3^{-3}=\frac{1}{27})। भाग देने पर (\frac{10}{3}) मिलता है।
