यदि \(\frac{31}{2^a5^b}\) का दशमलव ठीक (10) स्थानों पर समाप्त होता है और (b>a) है तो (b) का मान क्या होगा?
If \(\frac{31}{2^a5^b}\) terminates exactly after (10) decimal places and (b>a), what is the value of (b)?
Explanation opens after your attempt
Correct Answer
C. (10)
Concept
When (b>a), the larger exponent is (b). For exactly (10) decimal places, (b=10).
Why this answer is correct
The correct answer is C. (10). When (b>a), the larger exponent is (b). For exactly (10) decimal places, (b=10).
Exam Tip
जब (b>a) है तो बड़ी घात (b) होगी। ठीक (10) दशमलव स्थानों के लिए (b=10) होना चाहिए।
