Cho abc # 0 va a+b-c/c=b+c-a/a=c+a-b/b
Tính P = a+b/a*b+c/b*c+a/c
Cho abc # 0 va a+b-c/c=b+c-a/a=c+a-b/b
Tinh P=(1+b/a)(1+c/d)(1+a/c)
cho 3 so a,b,c khac 0 va thoa man a+b-c/c=a+c-b/b=b+c-a/a
tinh gia tri bieu thuc P=(a+b)(b+c)(c+a)=abc
cho a,b,c khac 0 va a+b-c/c =b+c-a/a=c+a-b/b tinh p=(1+b/a)(1+c/b)(1+a/c)
cho a,b,c la 3 so khac 0 va a+b+c# 0
Thỏa mãn : a/b+c = b/c+a = c/a+b
Tinh gia tri bieu thuc : P = b+c/a + c+a/b + a+b/c
cho a,b,c >0.so sanh A=a/b+b/a va a/a+b+b/b+c+c/c+a
Cho a+b+c+d khac 0 va a/b+c+d=b/a+c+d=c/a+b+d=d/a+b+c.
Tinh gia tri A= a+b/c+d + b+c/a+d + c+d/a+b + d+a/b+ch
Cho a,b,c khac 0 va a+b+c=0. Tính (1+a/b)(1+b/c)(1+c/a)
cho a b c khac 0 va a-b-c=0 tinh gia tri bieu thuc A=(1-c/a) (1-a/b) (1+b/c)
