To find the square number of 19, we need to multiply 19 by itself. Here is the step-by-step process:
1. Understand the problem: We need to find the square of the number 19. Squaring a number means multiplying the number by itself.
2. Write down the multiplication: We are multiplying 19 by 19.
[tex]\[
19 \times 19
\][/tex]
3. Perform the multiplication:
Let's break it down to make it easier:
- First, multiply 9 (the units place) by 19:
[tex]\[
9 \times 19 = 171
\][/tex]
- Multiply 10 (the tens place, representing 1 from 19) by 19:
[tex]\[
10 \times 19 = 190
\][/tex]
- Now add the two results together:
[tex]\[
171 (from 9 \times 19) + 190 (from 10 \times 19) = 361
\][/tex]
4. Write down the final result: The result from performing the multiplication is 361.
Thus, the square number of 19 is 361.
