Answer : the smallest positive integer k is ......
2. find the value of k such that the remainder is the greatest
k/13= 11Rx
K=
Find the least integer number x such that 4/x-3 is the integer number.
Find the largest 3-digit integer m such that when m is divided by 3, 7, 11 the remainders are 1, 3, and 8 respectively.
.........
=>a+2 chia hết cho 3;7;11
=> a+2 thuộc ước của(3;7;11)
..........
phần còn lại các bạn tự giải nhé
Chúc học tốt ^^
cho mình sửa lại chút
A+2 thuộc bội chung của (3;7;11)
Sorry
sorry mình giải sai bước đầu rồi
nhưng cách giải tương tự vậy đó
cứ giải theo mìk nha
Question 8: Find four integer numbers a,b,c,d such that a + b + c + d = 1 a + c + d = 2 a + b + d = 3 a + b + c = 4 Answer: (a;b;c;d)=(
Toán tiếng anh: Let a, b, c be the possible integer such that ab+bc=518 and ab-ac=360. Find the largest possible value of the product abc
Find four integer numbers a,b,c,d such that
a + b + c + d = 1
a + c + d = 2
a + b + d = 3
a + b + c = 4
Answer: (a;b;c;d)=
vì a+b+c+d=1 mà a+b+c=4 => d = -3
tương tự ta đc b=-1 ; c= -3 =>a=8
b=1-2=-1
c=1-3=-2
a=4-(-1+-2)=
d=1-a+b+C
Find the smallest integer value of x such that: 2x+3>5
Find four integer numbers a,b,c,d such that
a + b + c + d = 1
a + c + d = 2
a + b + d = 3
a + b + c = 4
Answer: (a;b;c;d)=()
Question 8:
Let P = \(\frac{2x}{x+3}-\frac{x+1}{x-3}+\frac{3-11x}{9-x^2}\). Find the smallest integer x such that P is also an integer.
\(x\ne\pm3\)
\(P=\frac{2x\left(x-3\right)}{\left(x-3\right)\left(x+3\right)}-\frac{\left(x+1\right)\left(x+3\right)}{\left(x-3\right)\left(x+3\right)}+\frac{11x-3}{\left(x-3\right)\left(x+3\right)}\)
\(=\frac{x^2+x-6}{\left(x-3\right)\left(x+3\right)}=\frac{\left(x+3\right)\left(x-2\right)}{\left(x+3\right)\left(x-3\right)}\)
\(=\frac{x-2}{x-3}=1+\frac{1}{x-3}\)
P is an integer if and only if 1 is divisible by \(x-3\)
Therefore \(x-3=\left\{-1;1\right\}\Rightarrow x=\left\{2;4\right\}\)
\(\Rightarrow x_{min}=2\)
