To find the numerical equivalent of \( 72 \cdot 73 \), you can use the formula for the product of two consecutive integers, which is given by:
\[ n(n+1) = n^2 + n \]
In this case, let \( n = 72 \):
\[ 72 \cdot 73 = 72^2 + 72 \]
Now, calculating \( 72^2 \):
\[ 72^2 = 5184 \]
Now adding \( 72 \):
\[ 72^2 + 72 = 5184 + 72 = 5256 \]
Thus, the numerical equivalent of \( 72 \cdot 73 \) is \( \boxed{5256} \).
