问题描述:

根号8分之3 - (-3分之4根号2分之27+3根号6分之1)
根号0.2m + m分之1根号5m^3 - m根号125分之m
6分之1根号5分之8 * (-5根号5分之18)
根号2x * 根号2y * 根号x
(根号mn - 根号n分之m)/根号n分之m (n大于0)

3/(8^0.5)-(4/(-3)*(27/(2^0.5))+3/(6^0.5))=3/(2*(2^0.5))+(4/3)*(27/(2^0.5))-3/(6^0.5)=(3/2+(4/3)*(27)-3/(3^0.5))/(2^0.5)=(3/2+4*9-(3^0.5))/(2^0.5)=(75-2*(3^0.5))/(2*2^0.5)=75/(2*2^0.5)-(3/2)^0.5) 根号0...
