√64/9乘以√169/144=?3/1√90乘以2/1√40=?√18除以{3√2乘以2√2}=?-√1.1/√2.7乘以√33=?
√64/9乘以√169/144=?3/1√90乘以2/1√40=?√18除以{3√2乘以2√2}=?-√1.1/√2.7乘以√33=?
√64/9乘以√169/144=?3/1√90乘以2/1√40=?√18除以{3√2乘以2√2}=?-√1.1/√2.7乘以√33=?
√64/9乘以√169/144
=√(64/9)*√(169/144)
=8/3*13/12
=26/9
3/1√90乘以2/1√40
= √(90)/3*√(40)/2
=3√(10)/3*2√(10)/2
=√(10)*√(10)
=10
√18除以{3√2乘以2√2}
=√(18)/{6√2*√2}
=3√(2)/{6*2}
=√(2)/4
√1.1/√2.7乘以√33
=√(1.1)*[√(33)/√(2.7)]
=√(1.1)*[√(11)/√(0.9)]
=√(1.1)*[√(110)/√(9)]
=√(1.1*110)/3
=√(11*11)/3
=11/3
√64/9乘以√169/144
=8/3*13/12
=26/9
3/1√90乘以2/1√40
=3√10/3*2√10/2
=√10*√10
=10
-√1.1/√2.7乘以√33
=√(2.7*33/1.1)
=√81
=9

1乘以2乘以3+2乘以3乘以4+3乘以4乘以5+...+7乘以8乘以9
=3乘以2乘以1,=4乘以3乘以2乘以1,=5乘以4乘以3乘以2乘以1,那么100!除以99!
6/7乘以( )=3/5乘以( )=9乘以( )=0.2乘以( )=1
7乘以9=63,8乘以8=64,11乘以13=143,12乘以12=144,24乘以26=624,25乘以25=625.这些式子有什么规律
2乘以√(12)除以(1/2)乘以√50乘以(1/2)乘以√(3/4)我算的是120√3.
7乘以9=63,8乘以8=64,11乘以13=143,12乘以12=144,有什么规律
1+2乘以3+4乘以5+6乘以7+8乘以9=1005 在上面各式当中添上适当的括号使等式成立
5乘以5等于0乘以1乘以100+25;15乘以15等于1乘以2乘以100+25;25乘以25等于2乘以3乘以100=25;猜测地N个算式应表示为:
1乘以2乘以3分之1加2乘以3乘以4分之1,一直到9乘以10乘以11分之1的简便运算做么做
4乘以(3x-1)的平方+9乘以(3x+1)的平方=0
1除以(1乘以2乘以3)加上1除以(2乘以4乘以3)加上1除以(3乘以4乘以5)加上.1除以(8乘以9乘以10)
计算:1/1乘以3+1/2乘以4+1/3乘以5+...+1/9乘以11
