0.125^300乘2^901 4-12(x-y)+9(y-x)^2 因式分解
0.125^300乘2^901 4-12(x-y)+9(y-x)^2 因式分解

0.125^300乘2^901 4-12(x-y)+9(y-x)^2 因式分解
0.125^300×2^901
=0.125^300×2^900×2
=0.125^300×(2³)^300×2
=0.125^300×8^300×2
=(0.125×8)^300×2
=1^300×2
=1×2
=2
4-12(x-y)+9(y-x)²
=9(x-y)²-12(x-y)+4
=[3(x-y)-2]²
=(3x-3y-2)²
明白请采纳,
有新问题请求助,

你好

0.125^300×2^901
=1/8^300×2^901
=1/2^900×2^900 ×2
=(1/2×2)^900 ×2
=1×2
=2

4-12(x-y)+9(y-x)^2
=4-12(x-y)+9(x-y)^2
=[2-3(x-y)]^2
=(2-3x+3y)^2
