用多功能计算器怎样把弧度转化成度数

设 有X台计算器．1/6X-15+7/8X=X4/24X+21/24X-X=151/24X=15X=360答:一共有360个计算器设 这列客车到达A站前有X人.X-1/4X+24=7/8X3/4X-7/8X=-246/8X-7/8X=-24-1/8X=-24X=192答:这列客车到达A站前有192人.设 共有X包水...

按log键后 输入底数和对数 按等号就可以了!

一定是无理数啊
这个是近似值,无法显示那么多位数,所以造成你不能验算
无理数一般不要验算拉,

先输入底数 然后找一个功能键 X然后右上角有个小Y的 按了以后再按指数 再按等于 就得到结果了
