SS A vs B
\(A=\dfrac{54.107-53}{53.107+54}\)
\(B=\dfrac{135.169-133}{134.269+135}\)
ĐỀ : Cho \(M=\dfrac{54.107-53}{53.107-54}\); \(N=\dfrac{135.269-133}{134.269-135}\)
So sánh M vs N
\(M=\dfrac{54.107-53}{53.107-54}=\dfrac{53\left(107-1\right)+107}{53\left(107-1\right)-1}=\dfrac{53.106-1+108}{53.106-1}=1+\dfrac{108}{53.106-1}\)
\(N=\dfrac{135.269-133}{134.269-135}=\dfrac{134\left(269-1\right)-1+270}{134\left(269-1\right)-1}=1+\dfrac{270}{134.268-1}\)
\(M-N=\dfrac{108}{53.106-1}-\dfrac{270}{134.268-1}\)
\(M-N=\dfrac{2}{2.53^2-1}-\dfrac{5}{8.67^2-1}>\dfrac{5}{10.53^2-1}-\dfrac{5}{8.67^2-1}>0\)
M>N
so sánh A=54.107-53/53.107+54 và B=135.269-133/134.269+135
So sánh
A= 54.107-53/53.107+54
B= 135.269-133/134.269+135
so sánh
A=54.107-53/53.107+54 và B=135.269-133/134.269+135
A<B . K CHO MÌNH NHA
So sanh phan so:
a)54.107-53/53.107+54=A
B=135.269-133/134.269+135
Ta thấy :
A=\(\frac{54.107-53}{53.107+54}=\frac{53.107+107-53}{53.107+54}=\frac{53.107+54}{53.107+54}=1\)
B=\(\frac{135.269-133}{134.269+135}=\frac{134.269+269-133}{134.269+135}=\frac{134.269+136}{134.269+135}>1\)
Vậy A < B
A = \(\frac{54.107-53}{53.107+54}\) và B = \(\frac{135.269-133}{134.269+135}\)
so sánh
A=54.107-53/53.107+54 và B=135.269-133/134.269+135
mọi người ghi luôn cả cách làm bài hộ mình nha
vi 53/53.107 =1/107 nenA > 54.107+54 < 135.269 < B
So sánh
G=54.107-53/53.107+54 và H=135.269-133/134.269+135
