根号72乘以根号128等于几？

根号128等于: √128=≈11.31。根号是一个数学符号。根号是用来表示对一个数或一个代数式进行开方运算的符号。若aⁿ=b，那么a是b开n次方的n次方根或a是b的1/n次方。开n次方手写体和印刷体用表示，被开方的数或代数式写在符号左方√￣的右边和符号上方一横部分的下方共同包围的区域中，而且不能出界。在实数范围内：（1）偶次根号下不能为负数，其运算结果也不为负。（2）奇次根号下可以为负数。不限于实数，即考虑虚数时，偶次根号下可以为负数，利用【i=√-1】即可。

具体回答如下：√128=√（2×2×2×2×2×2×2）=8√2≈11.31写根号：先在格子中间画向右上角的短斜线，然后笔画不断画右下中斜线，同样笔画不断画右上长斜线再在格子接近上方的地方根据自己的需要画一条长度适中的横线，不够再补足。被开方的数或代数式写在符号左方v形部分的右边和符号上方一横部分的下方共同包围的区域中，而且不能出界，若被开方的数或代数式过长，则上方一横必须延长确保覆盖下方的被开方数或代数式。

=根号下64乘根号下2=8倍根号2

128=64*2.所以根号128等于8根号2

是无理数。证明：因为根号下128等于8倍根号2，又因为8倍根号2是无理数，所以根号下128是无理数。

根号128=根号64*根号2=8*根号2

128=(√128)²=(8√2)²

拿出来开玩笑的吧。2的7次方，开出来是无理数。

手工开根号法,只适用于任何一个整数或者有限小数开二次方. 因为网上写不出样式复杂的计算式,所以只能尽量书写,然后通过口述来解释: 假设一个整数1456456,开根号首先要从个位开始,每两位数做个标记,这里用"表示,那么标记后变成1"45"64"56.然后根据你要开的小数位数在小数点后补0,这里的举例开到整,则补2个0,(原因等明白该做法后自会理解),解法如下: 解法中需要说明的几个问题: 1,算式中的....没有意义,是因为网上无法排版,为了能把版式排得整齐点而加上的 2,为了区别小数点，所以小数点用。表示，而所有的.都是为了排版需要 3、除了1"45"64"56中的"有特殊意义，在解题中有用处外，其他的"都是为了排版和对起位置，说明数字来源而加的，取消没有任何影响 ...........1..2..0..6。8 .........----------------------- .....1../..1"45"64"56.00........(1) .............1 ............-------- .......22..|.45.................(2) ..............44 ..............-------- ........240.|.1"64..............(3) ....................0 ...............--------- .......2406.|.1"64"56...........(4) ..................1"44"36 .................----------- ........24128.|.20"20"00........(5) ....................19"29"74 ..................---------- .......................10"26 其中第(1)步的意思是对左起第一个"号前的数字进行开方,即本题中的1进行开方.并将数字写在上面. 第(2)步的意思是将第二个"号和第一个"号之间的数字,即45,写下来作为被除数,把上一步已经得到并写在上面的数字1乘以20作为除数的一部分,另一部分就得通过判断,得到一个数字a,使得除数为(1*20+a),同时商也为a,本步骤中,判断得到a应为2,所以除数是22,而2作为商写到了上面,1的右边. 第(3)步,把上一步除法计算的余数1移下来,同时把第三个"号和第二个"号之间的数字64也移下来,组成数字164作为被除数,然后重复上面的方法,把之前写到上面的数字12乘以20再加上一个可以作为本步骤的商的数字,组成除数.因为经过判断,本步骤只有0符合条件,所以除数是240,而商是0写到上面,164作为余数向下移. 第(4)步,如果前面能看懂的话,这一步其实只是前面的重复,把164和56都移下来组成被除数16456,然后120乘以20再加上6组成除数,同时6本身就是商,得到余数2020. 第(5)步依然是重复,需要特殊说明的是,对于小数点后面的数字,用0补位数就可以了,依然是两位加个"号,做法不变. 上面就是基本步骤了,总结起来就是先分位数,然后对第一个分位数字进行开方,如果有余数就想下移,和第二个分位组成被除数.而除数是之前已经得到的商乘以20加上某数字组成,而这个数字要在这个步骤中作为商出现的,所以这个数字是0-9中的哪个数字,得进行心算或口算来判断,得到余数再下移,一直重复到得到答案. 其中还要说明的是每一步得到的余数一定不能比除数大,也不能小于0,不然是无效的,说明选择做商的数字是不对的. 网上找的，望采纳~！

可以表白的数学公式：128根号e980、[(n+52.8)×5–3.9343]÷0.5-10×n、X2+(y+3√X2)2=1、r=a(1-cosθ)或r=a(1+cosθ)、x2+(y-3√x2)2=1。128根号e980。I Love You的数学公式最早来源于韩国歌手K.will的一首MV，叫《I need you》。女孩在黑板上写了一个数学公式“128根号e980”，让男主角解答，男主角冥思苦想都算不出来，于是女孩拿起刷子擦掉公式的上半部分，就变成了英文的 I Love You。

128√98=128√7*7*2=128*7√2=896√2

8×128=8×2x64=16×64=(4x8)^2所以根号8x128=根号(4x8)^2=4×8=32

√128 = 8√2 ≈ 11.314

8根号2

根号128=√128=8√2

约等于11.3

√128=8√2

128 =2^7 所以,四次根号下128得 2*四次根号下8.

128显然不是完全平方数进行分解得到等于2*64那么就是正负2根号8的平方使用计算器的话即约等于正负11.314的平方

3√128=3×√(8²×2)=3×8√2=24√2。

2(3.5)次幂就是2（3）次幂*根号2=8*1.4142136=11.3137085其次你可以用windows下的科学计算器去算：开始菜单--程序--附件--计算器记住一定用科学计算器哦Goodluck

128根号下没有负数，因为根号下的绝对值不可能小于0。

√32+√128 =√4*4*2+√4*4*2*2*2 =4√2+8√2 =12√2

√32+√128 =√4*4*2+√4*4*2*2*2 =4√2+8√2 =12√2

2000kg等于2吨。其中1kg等于0.001吨，而1吨等于1000kg。吨与千克这两个单位都属于重量单位，并且也是我们日常生活中会用的比较多的重量单位之一。吨经常会用来形容一些比较大的物体种类，比如汽车、钢材等。而千克由于表示的数量比较小，则可以形容更多东西，比如体重以及食物重量等。以上就是关于问题“2000kg等于多少吨”的解答，接下来是关于吨与千克的补充内容，有兴趣的观众欢迎继续观看。 关于吨与千克的补充 1、吨的介绍：吨又可以被人们称为兆克或是公吨，吨是我国承认的重量单位之一，同时也是公制单位之一。 2、使用吨的地区：全世界大部分国家及地区都会使用吨作为重量单位，但是也会少部分国家或地区不承认吨作为重量单位。 3、千克的介绍：千克是国际单位中的重量基本单位之一，同时千克也是所有国际重量单位中的转换标准。 4、重量的标准器：早在国际组织制定重量标准器时，最开始是想用克作为标准器的，但是奈何当时的工艺水平没有办法生产非常精确的克精装器，所以当时就改成制作千克标准器。 公斤的单位是千克吗

1、2000克是4斤。1000克=1千克=1公斤=2斤。 2、一克是18×14074481个C－12原子的质量。一克的重量大约相当于一立方厘米水在室温中的重量。 3、中国自周代开始有重量单位：斤、两、钱、分。也称为「司马斤」、「司马两」等，计量的工具叫做「司马秤」，这一标准也叫「司马平制标识」。

楼上开玩笑，哪有那么快60000÷3600=16.67米/每秒答：每秒是16.67米
