To determine the number of ways to distribute 30 balls of 10 different colors, with 3 identical balls for each color, into 10 similar boxes, we can use combinatorial methods. Let's analyze the problem step by step.

1. Understanding the problem:

   • We have 30 balls in total, with 10 different colors and 3 balls of each color.
   • We need to distribute these 30 balls into 10 identical boxes.

2. Applying combinatorial principles:

   • Because the boxes are identical, the problem simplifies. Each color has three balls, which need to be distributed among the boxes.

3. Distribution of each color:

   • For each color, we need to distribute 3 identical balls into 10 identical boxes.
   • The number of ways to distribute $k$ identical balls into $n$ identical boxes is given by the formula for combinations with repetition: $\binom{n+k-1}{k}$.
   • In our case, for one color, it would be $\binom{10+3-1}{3} = \binom{12}{3}$.

4. Calculating $\binom{12}{3}$: $\binom{12}{3} = \frac{12!}{3!(12-3)!} = \frac{12 \times 11 \times 10}{3 \times 2 \times 1} = 220$

5. Considering all colors:

   • Since there are 10 different colors, and the distribution of each color is independent of the others, the total number of ways to distribute all the balls is $(\binom{12}{3})^{10}$.

6. Final calculation: $(\binom{12}{3})^{10} = 220^{10}$

Therefore, the total number of ways to distribute the 30 balls of 10 different colors into 10 identical boxes is $220^{10}$.
