答えの順番?というか、カッコの中身の順番は決まってるんですか??私の答えは合ってるということでいいんでしょうか、、?
111 64x6-86
=
{(22)³} -(y)²
= { (2x) ³ + y³ } { (2x) ³ - y³
}
(2x+y) (4x²-2xy + y = ) ( 2x - y ) (4x²+ 2 x y + y²)
4 (1)与式=(2x)-y°={(2x)}2-(y3)2
={(2x)³ + y³}{(2x)³- y³)
左
=(2x+y)(4x2-2xy + y²)(2x-y)(4x2+2xy + y²)
=(2x+y)(2x − y)(4x²-2xy + y²)(4x2+2xy + y²)
-
別解与式=(2x)-y°={(2x)2}3-(y2)3
={(2x)2 y2}{(2x)4+ (2x)². y²+y4}
-
= {(2x)² — y²}|{{(2x)² + y²]² = (2x)² y²)
(+税)
=(2x+y)(2x-y)(4x²-2xy + y²) (4x²+2xy + y²)
