Consider the following statements
I : The number of non-trivial even divisors of the number \(2^{\alpha_1} 3^{\alpha_2} 4^{\alpha_3} 5^{\alpha_4} 6^{\alpha_5}\), is \(\left(\alpha_1+1\right)\left(\alpha_2+1\right)\left(\alpha_3+1\right)\left(\alpha_4+1\right)\left(\alpha_5+1\right)-2\)
II : The number of non-trivial odd divisors of the number \(2^{\alpha_1} \cdot 3^{\alpha_2} \cdot 4^{\alpha_3} \cdot 5^{\alpha_4} \cdot 6^{\alpha_5}\), is \(\alpha_2+\alpha_4+\alpha_5+\alpha_2 \alpha_4+\alpha_4 \alpha_5\). Then

  1. A I is false and II is false
  2. B I is true and II is true
  3. C I is false and II is true
  4. D I is true and II is false
Verified Solution

Answer & Solution

Correct Answer

(C) I is false and II is true

Step-by-step Solution

Detailed explanation

Given number \(=2^{\alpha_1} 3^{\alpha_2} 4^{\alpha_3} 5^{\alpha_4} 6^{\alpha_5}\) \(=2^{\alpha_1+2 \alpha_3+\alpha_5 3^{\alpha_2}+\alpha_5 5^{\alpha_4}}\) Number of non-trivial even divisors…
