从1开始,每个自然数的平方,如果为两位数,则左右互换
1×1=1 1
2×2=4 4
3×3=9 9
4×4=16 61
5×5=25 52
6×6=36 63
7×7=49 94
8×8=64 46

所以是46

解:
填46

规律:把各个数个位与十位倒过来

1 4 9 16 25 36 49 下一个是 64
所以个位与十位倒过来得
1 4 9 61 52 63 94 46

规律是:
1、前三个数是平方数的结果。
2、后面的数是平方数的结果,将数字的位置颠倒。
1 4 9 61(16 ) 52(25) 63(36) 94(49) 46(64)

1、4、9、61、52、63、94、( )
1是1²
4是2²
9是3²
61是4²=16的个位和十位互换得到的
52是5²=25的个位和十位互换得到的
63是6²=36的个位和十位互换得到的
94是7²=49的个位和十位互换得到的
所以:括号内应该是46,即8²=64的个位和十位互换得到的

46
61和52颠倒过来就是16和25,分别是4和5的平方
1,4,9分别是1,2,3的平方
由此可以得出前三个数是1,2,3的平方,接下来三个是4,5,6,7平方颠倒过来,接下来三个是8,9的平方
由题意得:1,4,9,61,52,63,94, 46…

几道六年级数学题!速度!要过程!~

(1)0.72 0.75
(2)第一π*4*4*4=64π 第二π*3*3*7=63π 第三π*2.5*2.5*10=62.5π 所以第一个多
(3)3.14*3*3*5*1=141.3千克。所以盛不了150千克
(4)(3.14*1.25*1.25*9.25)/50≈0.9立方厘米
