解答
x·x·x²·x的4次方+(-2x²)的4次方-2x的8次方
=x的8次方+16x的8次方-2x的8次方
=15x的8次方
-2xy·(2x²y)³·(-2x的5次方z)
=4x的6次方yz*8x的6次方y的3次方
=32x的12次方y的4次方z

计算2x【3+1】x【3²】x【3的4次方+1】x【3的8次方+1】
x的四次方+2x²-8 因式分解
若|2x+8|+(y-0.25)²=0求x的2011次方 乘 y的2012次方
计算:x的8次方÷x²-(-2x²)²·x²
1.已知3的x次方=8,3的y次方=2.求3的 2x-3y 方的值 2.已知x²+x负2次方=4,求x四次方+x负四方值
2cos(2x+π)等于
