解答
原式=√(6/16)+(3/4)√(54/4)-3√(6/36)
=√6/4+(3/4)3√6/2-3√6/6
=(1/4+9/8-1/2)√6
=7√6/8
推荐
- 1*2*4+2*4*8+3*6*12分之1*3*24+2*6*48+3*9*27
- 先找规律再填数2分之1,4分之3,8分之9,16分之27,(),(). 3分之2,3分之1,6分之
- 1*3*9+2*6*18+3*9*27+4*12*36分之1*2*4+2*4*8+3*6*12+4*8*16
- 6.73-2又17分之8+(3.27-1又17分之9)=
- 简算;6.73-2 又17分之8+(3.27-1又17分之9)
- 已知x1,x2是一元二次方程3x*x+2x-6=0的两个根,不解方程,求x1*x1+x1x2+x2*x2和x2/x1+x1/x2的值
- 为什么是how much does it weigh 而不是how many..
- Changes took place in the Scottish universities which had a major impact on the Society.For example
