നെ ലഘൂകരിച്ചാൽ കിട്ടുന്നത് ?

• A. 36/25
• B. 25/36
• C. 18/25
• D. 25/18

Answer 1

Answer:

D. 25/18

${[\frac{2^5 \times 2^3 \times 3^2 \times 3^4 \times 5^2}{2^6 \times 3^3 \times 5^4 \times 6}]}^{-1}$

$={[\frac{2^5 \times 2^3 \times 3^2 \times 3^4 \times 5^2}{2^6 \times 3^3 \times 5^4 \times 2 \times 3}]}^{-1}$

$={[\frac{2^8 \times 3^6 \times 5^2}{2^7 \times 3^4 \times 5^4 }]}^{-1}$

$={[\frac{2 \times 3^2 }{ 5^2 }]}^{-1}$

$=\frac{25}{18}$
