Answer 2

To solve this expression, we can simplify it step by step. First, let's simplify the factorials in the expression:

$\frac{25! + 28!}{24!}$

Using the fact that $n! = n \times (n-1)!$, we can rewrite the expression:

$\frac{25 \times 24! + 28 \times 27!}{24!}$

Now, we can cancel out the common $24!$ in the numerator and denominator:

$25 + \frac{28 \times 27!}{24!}$

Using the same factorial simplification, we get:

$25 + \frac{28 \times 27 \times 26 \times 25!}{24!}$

Again, cancel out the common $24!$ in the numerator and denominator:

$25 + 28 \times 27 \times 26$

Now, calculate the multiplication:

$25 + 19656$

$= 19681$

So, the simplified value of the expression $\frac{25! + 28!}{24!}$ is $19681$.
