Hãy nhập câu hỏi của bạn vào đây, nếu là tài khoản VIP, bạn sẽ được ưu tiên trả lời.
\(A=\frac{67^{2016}}{67^{2016}}-11=1-11=-10< 0\)
\(\Rightarrow A< 0\)
\(B=\frac{67^{2016}+3}{67^{2016}+2}>0\)
\(\Rightarrow B>0\)
Vậy \(B>A\)
\(\left(\frac{1}{3}+\frac{12}{67}+\frac{13}{41}\right)-\left(\frac{79}{67}-\frac{28}{41}\right)\)
\(=\frac{1}{3}+\frac{12}{67}+\frac{13}{41}-\frac{79}{67}+\frac{28}{41}\)
\(=\left(\frac{12}{67}-\frac{79}{67}\right)+\left(\frac{13}{41}+\frac{28}{41}\right)+\frac{1}{3}\)
\(=\left(-1\right)+1+\frac{1}{3}\)
\(=\frac{1}{3}\)
\(\left(\dfrac{1}{3}+\dfrac{12}{67}+\dfrac{13}{41}\right)-\left(\dfrac{79}{67}-\dfrac{28}{41}\right)\\ =\left(\dfrac{103}{201}+\dfrac{13}{41}\right)-\dfrac{1363}{2747}\\ =\dfrac{6836}{8241}-\dfrac{1363}{2747}\\ =\dfrac{1}{3}\)
\(\left(\dfrac{1}{3}+\dfrac{12}{67}+\dfrac{13}{41}\right)-\left(\dfrac{79}{67}-\dfrac{28}{41}\right)\\ =\dfrac{1}{3}+\dfrac{12}{67}+\dfrac{13}{41}-\dfrac{79}{67}+\dfrac{28}{41}\\ =\dfrac{1}{3}+\left(\dfrac{12}{67}-\dfrac{79}{67}\right)+\left(\dfrac{13}{41}+\dfrac{28}{41}\right)\\ =\dfrac{1}{3}-\dfrac{67}{67}+\dfrac{41}{41}\\ =\dfrac{1}{3}-1+1\\ =\dfrac{1}{3}\)
\(\left(\frac{1}{3}+\frac{12}{67}+\frac{13}{41}\right)-\left(\frac{79}{67}-\frac{28}{41}\right)\)
=\(\frac{1}{3}+\frac{12}{67}+\frac{13}{41}-\frac{79}{67}+\frac{28}{41}\)
\(=\frac{1}{3}+\left(\frac{12}{67}-\frac{79}{67}\right)+\left(\frac{13}{41}+\frac{28}{41}\right)\)
\(=\frac{1}{3}-1+1\)
\(=\frac{1}{3}\)
(1/3+12/67+13/41)-(79/67-28/41). =1/3+12/613/41-79/67+28/41. =1/3+(12/67-79/67)+(13/41+28/41) =1/3+(-1)+1=1/3+0. =1/3
\(\dfrac{2}{67}-\left(\dfrac{3}{7}+\dfrac{2}{67}\right)\\ =\dfrac{2}{67}-\dfrac{215}{469}\\ =\dfrac{-3}{7}\)
( -4 ) . 3 . ( -125 ) . 25 . ( -8 )
= [ -4 . 25 ] . [ -125 . ( -8 ) ] . 3
= -100 . 1000 . 3
= -100 000 . 3
= -300 000
( -67 ) . ( 1 - 301 ) - 301 . 67
= ( -67 ) . 1 - 301 - 301 . 67
= -67 . 1
= -67
a, ( -4 ) . ( +3 ) . ( -125 ) . ( +25 ) . ( -8 )
= ( - 4 ) . ( + 25 ) . ( - 125 ) . ( - 8 ) . ( + 3 )
= 100 . 1000 . 3
= 100000 . 3
= 300000
b, ( -67 ) . ( 1 - 301 ) - 301 . 67
= ( - 67 ) . 1 + 67 . 301 - 301 . 67
= -67 . 1
= - 67
34/79 + 78/67 xấp xỉ 1.6 nha bạn
34/97 + 65/34 = 7461/3298
1/3 + 27/67 = 148/201
3+67=70 nhé bạn
70 nhé bạn đó nhé
