证明或否定 [tex=2.643x1.143]lc4c9csR/e3Mon88xb+thiZI5h/Fk4isxf+SZ1aZ5x8=[/tex]是循环群.
举一反三
- 在 [tex=2.643x1.143]lc4c9csR/e3Mon88xb+thiZI5h/Fk4isxf+SZ1aZ5x8=[/tex]中, [tex=7.5x1.357]lGvf6x65buWcnG0kFnX6jvR65ekoF9TlYFHx9oxp+cDCxWFngmI3lGnFmA9d7vTl[/tex] 证明: [tex=0.5x1.0]3EF1VcotinZAjtQqtSWaxw==[/tex] 是一个素理想, 但不是极大理想.
- set1 = {x for x in range(10)} print(set1) 以上代码的运行结果为？ A: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} B: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,10} C: {1, 2, 3, 4, 5, 6, 7, 8, 9} D: {1, 2, 3, 4, 5, 6, 7, 8, 9,10}
- 求不定积分[img=115x46]17da65382f8e1b9.png[/img]； （ ） A: x - (5*log(x + 1))/4 - (3*log(x - 3)) B: (5*log(x + 1))/4 - (3*log(x - 3)) C: x - (5*log(x + 1))/4 - (3*log(x - 3))/4 D: (5*log(x + 1))/4 - (3*log(x - 3))/4
- A=[1 2 3 4 5 6 7 8 9]A(5)=[]A=1 4 7 5 8 3 6 9
- >>>x= [10, 6, 0, 1, 7, 4, 3, 2, 8, 5, 9]>>>print(x.sort()) 语句运行结果正确的是( )。 A: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10] B: [10, 6, 0, 1, 7, 4, 3, 2, 8, 5, 9] C: [10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0] D: ['2', '4', '0', '6', '10', '7', '8', '3', '9', '1', '5']
