To find the square of 39, you simply multiply 39 by itself. This operation is often referred to as "squaring" a number. So, let's break it down step by step.
Calculating 39 Squared
The mathematical expression for squaring a number is:
n² = n × n
In this case, we have:
39² = 39 × 39
Breaking Down the Multiplication
To make the multiplication easier, you can use the distributive property. This means you can break 39 into smaller parts. For example, you can express 39 as:
39 = 30 + 9
Now, using the distributive property:
39 × 39 = (30 + 9) × (30 + 9)
Applying the distributive property (also known as the FOIL method for binomials), we get:
- 30 × 30 = 900
- 30 × 9 = 270
- 9 × 30 = 270
- 9 × 9 = 81
Now, add all these results together:
900 + 270 + 270 + 81 = 1521
The Final Result
Thus, the square of 39 is:
39² = 1521
So, whenever you need to square a number, remember that it’s just multiplying the number by itself, and you can use various methods to simplify the calculation if needed. In this case, 39 squared equals 1521.
