解析 【解析】先将432化成为正$$ 3 \times 1 4 4 $$数的形式,利用二次 根式的化简求解即可. $$ \sqrt { 4 3 2 } = \sqrt { 1 4 4 \times 3 } = \sqrt { 1 4 4 } \times \sqrt { 3 } = 1 2 \sqrt { 3 } $$. 故答案为:12$$ \sqrt { 3 } $$2. ...

图3 2、公式 =-2^2 返回 -2 的平方之所以为 4,是因为负号(-)的计算优先权大于乘方(^),即先 -2 再平方;公式 =A2^2 与 =-A2^2 返回 4 是同一意思;因此,如果负数的平方要返回负数,需要把数字和乘方用括号括起来,如 =-(A2^2) 或 =-(2^2)。
【解析】根式$$ \frac { \sqrt [ 3 ] { a ^ { 4 } } } { b \sqrt { b } } = a ^ { \frac { 4 } { 3 } } b ^ { - 1 - \frac { 1 } { 2 } } = a ^ { \frac { 4 } { 3 } } b ^ { - \frac { 3 } { 2 } } $$ 故答案为:$$ a ^ {...
