要去掉方程左边的根式,请对方程两边进行平方。 √x2=52x2=52 化简方程的两边。 点击获取更多步骤... 使用axn=axn,将x重写成x12。 (x12)2=52 化简(x12)2。 将(x12)2中的指数相乘。 运用幂法则并将指数相乘,(am)n=amn。 x12⋅2=52 约去2的公因数。
Radical equations may have one or more radical terms, and are solved by eliminating each radical, one at a time. We have to be careful when solving radical equations, as it is not unusual to findextraneous solutions, roots that are not, in fact, solutions to the equation. These solutions...
