\( \frac{4!\cdot8!}{5!\cdot7!} \) का सरल मान क्या है?
What is the simplified value of \( \frac{4!\cdot8!}{5!\cdot7!} \)?
Explanation opens after your attempt
Correct Answer
D. \( \frac{8}{5} \)
Concept
\( \frac{4!}{5!}=\frac{1}{5} \) and \( \frac{8!}{7!}=8 \), so the value is \( \frac{8}{5} \). Cancel separate ratios in multiplication.
Why this answer is correct
The correct answer is D. \( \frac{8}{5} \). \( \frac{4!}{5!}=\frac{1}{5} \) and \( \frac{8!}{7!}=8 \), so the value is \( \frac{8}{5} \). Cancel separate ratios in multiplication.
Exam Tip
\( \frac{4!}{5!}=\frac{1}{5} \) और \( \frac{8!}{7!}=8 \), इसलिए मान \( \frac{8}{5} \) है। गुणन में अलग-अलग अनुपात काटें।
