干郑裕835海宝在研究数学问题时发现了一个有趣的现象:(1)任选两组符合条件a+b=ab的正数a,b的值;(2)选(1)中两组a,b值中的一组值,验证海宝的结论:ba... -
仲夜武18512715279 ______[答案] (1)由a+b=ab,得到a=b(a-1),即b=aa−1,当a=2时,b=2;当a=3时,b=32;(2)若a=2,b=2,ab+ba=1+1=2,ab=4,则ba+ab比ab小2;(3)将b=aa−1代入ba+ab得:aa−1a+aaa−1=1a−1+a-1,代入ab得:a•aa−1=a2a−1...

干郑裕835A,B为n阶方阵,当E+AB可逆时,能否证明E+BA也可逆? -
仲夜武18512715279 ______[答案] 因为A,B为n阶方阵,当E+AB可逆,故(E+AB)^-1存在.因此(E+BA)(E-B[(E+AB)^-1]A)=E+BA-(E+BA)B[(E+AB)^-1]A=E+BA-(BE+BAB)[(E+AB)^-1]A=E+BA-B(E+AB)[(E+AB)^-1]A=E+BA-BA=E同理(E-B[(E+AB)^-1]A)(E+BA)=E所以E...

干郑裕835逻辑函数Y=AB'+A'B+BC'+B'C化为最简与或形式 -
仲夜武18512715279 ______[答案] 逻辑函数Y=AB'+A'B+BC'+B'C化为最简与或形式 Y=AB'+A'B+BC'+B'C= AB'+A'B(c+c')+BC'+(A+A')B'C = AB'+A'BC+A'BC'+BC'+AB'C +A'B'C =(AB'+AB'C)+(A'BC'+BC') +(A'B'C+A'BC) =AB'+BC'+A'C

干郑裕835在逻辑代数中A+A= ,A+AB= ,1+A= . -
仲夜武18512715279 ______[答案] (1)基本恒等式:A+A=A(表示A“或”A等于A) (2)吸收率:A+AB=A (3)基本恒等式:1+A=1. 这是因为逻辑变量的取值只能是0或者1.

干郑裕835已知1/a+1/b=7/a+b,求b/a+b的值(用两种不同方法求值) -
仲夜武18512715279 ______[答案] 解法 一:∵1/a+1/b=7/(a+b)∴(a+b)/ab=7/(a+b)∴(a+b)^2=7aba^2+b^2=5ab,∴b/a+a/b=(b^2+a^2)/ab=5ab/ab=5.解法二:∵1/a+1/b=7/(a+b)∴(a+b)/a+(a+b)/b=7∴1+b/a+a/b+1=7∴b/a+a/b=5.
