25. Yulduzcha o'rniga qanday raqam qo'yish mumkin: 126 = 2 · 3 · * · 7

To find the missing number, we need to solve the equation:

\( 126 = 2 \times 3 \times \text{*} \times 7 \)

First, multiply the known numbers:

\( 2 \times 3 \times 7 = 6 \times 7 = 42 \)

Now, divide 126 by 42 to find the missing number:

\( 126 \div 42 \)

We can see that \( 42 \times 3 = 126 \).

So, the missing number is 3.
