(1+√2)²(1+√3)²(1-√2)²(1-√3)²怎么算啊(1+√2)²(1+√3)²(1-√2)²(1-√3)²
(1+√2)²(1+√3)²(1-√2)²(1-√3)²怎么算啊
(1+√2)²(1+√3)²(1-√2)²(1-√3)²怎么算啊
(1+√2)²(1+√3)²(1-√2)²(1-√3)²怎么算啊
(1+√2)²(1+√3)²(1-√2)²(1-√3)²
=[(1+√2)(1-√2)]²[(1+√3)(1-√3)]²
=(1-2)²(1-3)²
=1×4
=4
(1+√2)²(1+√3)²(1-√2)²(1-√3)²
=4
答:
(1+√2)²(1+√3)²(1-√2)²(1-√3)²
=(1+√2)²(1-√2)²(1+√3)²(1-√3)²
=[(1+√2)(1-√2)]²[(1+√3)(1-√3)]²
=(1-2)²(1-3)²
=1*4
=4
