翻译:如果n和m是正整数,m是62的因子,那么 62=2x31 m is a factor of 62,=> m=1 or 2, or 31 or 62 n and m are positive integers 3n= 36/m m=1 =>n=12 m=2, =>n=6 m=31, =>n= 12/11 ( rej )m=62, =>n=6/31 (rej)the greatest possible number of integers...
51=3*17factor 52=4*13factor 53prime 54=2*3*9,factor 55=5*11,factor 56=7*8,factor 57=3*19,factor 58=2*29,not a factor and not a prime So 58 is the least positive integer that is not a factor of 25! and is not a prime number....

AStatement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
We show quite generally that at a temperature above any ordering tendency, strong interactions shift the QSH effect to quarter filling with a decrease of the spin Chern number by a factor of two. However, the spin susceptibility exhibits a peak indicating a tendency to ferromagnetism as the ...
(i) Let f(x)=2x^4+3x^3+a(x^2+x)+b.2x^2+3x-2=(2x-1)(x+2)f(1/2)=0 and f(-2)=0 since (2x-1)(x+2) is a factor of f(x).Since f(1/2)=0,2(1/2)^4+3(1/2)^3+a|(1/2)^2+(1/2)+b=01/8+3/8+a(3/4)+b=01/2+3/4a+b=02+3a+4b=0……...
