Question

教偶几道数学题，初一水平滴，聪明得哥哥姐姐弟弟妹妹阿姨叔叔爷爷奶奶 帮忙啦

1.某种细菌每0.5h便由1个分裂成2个，经过5h后，这种细菌由1个能分裂成多少个？
2.34.小明用计算机设计了一个计算程序，输入和输出得数据如下表:
输入 ... 1 2 3 4 5 ...
输出 ... 1/2 2/5 3/10 4/17 5/26...

当输入得数据是10时，输出得数据应为多少？

3.有一种24点游戏，其游戏规则是这样的：任取一副扑克牌，我们约定A为1，J、Q、K分别为11、12、13，并规定红色牌为正，黑色牌为负，任取4张牌，将这4张牌得数字进行加减乘除四则运算（每个数字用且只用1次），使其结果等于24，
例如，对红桃A， 红桃2，方块3，方块4可作运算（1+2+3）*4=24.【注意上述运算与4*（1+2+3）=24应视为相同方法得运算】
现有4张扑克牌红桃3，黑桃6，方块4，方块10，运用上述规则写出3种不同得运算式：
（1）
（2）
（3）
（4)另有4张扑克牌红桃3，黑桃6，方块10，运用上述规则写出3种不同得运算式 ，使其结果等于24

打得累死了，希望大家踊跃回答，帮助下偶吧，明天急用啊啊啊。
