 The teacher wrote a positive number \( x \) on the board and asked Kolya, Petya, and Vasya to raise this number to the 4th, 5th, and 20th power, respectively. It turned out that Kolya's number has at least 8 digits before the decimal point, and Petya's number has no more than 9 digits before the decimal point. How many digits are there before the decimal point in Vasya's number? Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags.<|im_end|>
