\(A=\frac{n-2}{n+3}\)

a) Để A là phân số khi n+3 khác 0 ( n thuộc Z)

vậy n khác -3 ( n thuộc Z ) thì A là phân số

b) Để A nguyên khi n-2 chia hết cho n+3

mà n+3 chia hết cho n+3

suy ra n+3-(n-2) chia hết cho n+3

suy ra 5 chia hết cho n+3

n +3 \(\in\left\{1;-1;5;-5\right\}\)

\(\in\left\{-2;-4;2;-8\right\}\)

Thử lại

\(B=\frac{10n-3}{4n-10}=\frac{\left(4n-10\right).\frac{5}{2}+22}{4n-10}\)

\(B=\frac{5}{2}+\frac{22}{4n-10}\Rightarrow B=\frac{5}{2}+\frac{11}{2n-5}\)

ĐỂ B đạt GTLN khi \(\frac{11}{2n-5}\)đạt GTLN, điều này xảy ra khi 2n - 5  là số nguyên dương nhỏ nhất,

tức là 2n-5=1 suy ra 2n=6 suy ra n=3

Khi đó \(B=\frac{10.3-3}{4.3-10}=\frac{27}{2}\)

Vậy B có GTLN là 27/2 khi n
