[(x+3)^3][(x-5)^6][(x-2)^7][(x+9)^4]小于0,求x的取值范围[(x+3)^3][(x-5)^6][(x-2)^7][(x+9)^4]小于0,求x的取值范围[(x+3)

[(x+3)^3][(x-5)^6][(x-2)^7][(x+9)^4]小于0,求x的取值范围
[(x+3)^3][(x-5)^6][(x-2)^7][(x+9)^4]小于0,求x的取值范围

[(x+3)^3][(x-5)^6][(x-2)^7][(x+9)^4]小于0,求x的取值范围
[(x+3)^3][(x-5)^6][(x-2)^7][(x+9)^4]小于0,
∵对任何数 (x-5)^6>0,(x+9)^4>0,只有考虑[(x+3)^3]、[(x-2)^7]两项.
1.如果(x+3)^30,原式0,那么(x-2)^7
