一般地,如果一个数的平方等于a,那么这个数叫做a的平方根(square root)或二次方根.这就是说,如果 x^2= a ,那么x叫做a的平方根几千年前。 古埃例如,3和-3是9的平方根,简记为士3是及人就已经知道了平方根9的平方根求一个数a的平方根的运算,叫做开平方 (extractionofsquareroot).我们看到,士3的平方...
A framing square may be used with wood or metal framing material. The framing square may be designed to exactly fit the size of the framing material, so as not to overhand off a side of the framing material. The framing square may, for example, allow for use when laying out door and ...
