15. (3 points) There are five numbers: $2$, $3$, $5$, $6$, and $7$. Use them to form one-digit or two-digit numbers to create an equation, resulting in $2010=$ $\qquad$ $2 \times 3 \times 5 \times 67$.

【Solution】Solution: Since the unit digit of 2010 is 0,
2 and 5 should be used as one-digit numbers,
and since 2010 is divisible by 3, 3 should also be used as a one-digit number,
so we get $2 \times 3 \times 5 \times 67=2010$.
Therefore, the answer is: $2 \times 3 \times 5 \times 67$.
