There is a bubble blowing machine that blows out exactly 100 soap bubbles at a time. After blowing out soap bubbles, half of them burst after 1 minute. After 2 minutes, there are (1/10) left unbroken, and after 3 minutes, only 2% are left. Break, these soap bubbles are all broken in less than 4 minutes, if the bubble blower blows once every minute, then when the new soap bubbles are blown out for the 10th time, at least how many soap bubbles are not broken? ．
有一个吹泡机，一次恰好吹出100个肥皂泡，肥皂泡吹出后，经过1分钟有一半破了，经过2分钟，还剩(1/10)没破，经过3分钟只剩下2%没破，这些肥皂泡不到4分钟全破，如果吹泡机每分钟吹一次，那么到第10次吹出新的肥皂泡时，没有破的肥皂泡至少有多少？．
