计算:(1)(-2x 4 ) 4 +3x 10 -(-2x 2 ) 3 +2x 4 -5(x 4 ) 3 (2)(-1) 2004 +(- 1 2

计算:(1)(-2x 4 ) 4 +3x 10 -(-2x 2 ) 3 +2x 4 -5(x 4 ) 3 (2)(-1) 2004 +(- 1 2 ) -2 -(3.14-π) 0 (3)2005 2 -2007×2003(利用乘法公式)
(1)原式=16x 16 +3x 10 ?(-8x 6 )+2x 4 ?5x 12 =16x 16 -24x 16 +10x 16 =2x 16
(2)原式猜颤饥=1+4-1=4;
(3)洞碰原式=2005 2 -(2005+2)穗返=2005 2 -2005 2 +4=4.
