To rewrite \(13 \times 19\) using the difference of two squares identity, we can express the multiplication in the form of \( (a - b)(a + b) \), where \( a \) is the average of the two numbers and \( b \) is the half of the difference between the two numbers.
First, let's find \(a\) and \(b\):
-
Calculate \(a\): \[ a = \frac{13 + 19}{2} = \frac{32}{2} = 16 \]
-
Calculate \(b\): \[ b = \frac{19 - 13}{2} = \frac{6}{2} = 3 \]
Now we can rewrite \(13 \times 19\) as: \[ (16 - 3)(16 + 3) \]
Thus, the answer is: \[ \boxed{(16 - 3)(16 + 3)} \]
