Hãy nhập câu hỏi của bạn vào đây, nếu là tài khoản VIP, bạn sẽ được ưu tiên trả lời.
\(\frac{a}{b}\cdot4+\frac{1}{16}=\frac{17}{6}\)
\(\frac{a}{b}\cdot4=\frac{17}{6}-\frac{1}{16}\)
\(\frac{a}{b}\cdot4=\frac{133}{48}\)
\(\frac{a}{b}=\frac{133}{48}:4\)
\(\frac{a}{b}=\frac{133}{12}\)
Cách giải của mình nhé
a/b*4+1/6=17/6
a/b*4 =17/6-1/6
a/b*4 =16/6
a/b =16/6 : 4
a/b =16/24
a/b =2/3
\(\frac{a}{b}\)x 4 + \(\frac{1}{6}\)= \(\frac{17}{6}\)
\(\frac{a}{b}\)x 4 = \(\frac{17}{6}\)- \(\frac{1}{6}\)= \(\frac{16}{6}\)
\(\frac{a}{b}\)= \(\frac{16}{6}\): 4
\(\frac{a}{b}\)= \(\frac{2}{3}\)
a: =35/17-18/17-9/5+4/5
=1-1=0
b: =-7/19(3/17+8/11-1)
=7/19*18/187=126/3553
c: =26/15-11/15-17/3-6/13
=1-6/13-17/3
=7/13-17/3=-200/39
Giúpppp mìnhh vớiiiiiiiiiiiiiiiiiiiiiiiii nhanhhhhhhhhhhh lênnnnnnnnnnnnnnnnn
a) \(\frac{75^3.3^7}{81^4.5^6}=\frac{5^3.3^3.5^3.3^7}{\left(3^4\right)^4.5^6}=\frac{5^6.3^3.3^7}{3^{16}.5^6}=\frac{3^{10}}{3^{16}}=\frac{1}{3^6}=\frac{1}{729}\)
b) \(\frac{6^6.4^2}{3^{12}.2^8}=\frac{2^6.3^6.\left(2^2\right)^2}{3^{12}.2^8}=\frac{2^6.3^6.2^4}{3^{12}.2^8}=\frac{2^{10}.3^6}{3^{12}.2^8}=\frac{2^2.1}{3^6}=\frac{4}{729}\)
c) \(\frac{34^5.2^5}{2^{14}.17^5}=\frac{2^5.17^5.2^5}{2^{14}.17^5}=\frac{2^{10}}{2^{14}}=\frac{1}{2^4}=\frac{1}{16}\)
Ta có : \(a-11b+3c⋮17\)
\(\Leftrightarrow19.\left(a-11b+3c\right)⋮17\)
\(\Leftrightarrow19a-209b+57c⋮17\)
\(\Leftrightarrow\left(17a-204b+51c\right)+\left(2a-5b+6c\right)⋮17\)
\(\Rightarrow\left(2a-5b+6c\right)⋮17\)(vì 17a - 204b + 51c đã chia hết cho 17 )
\(\RightarrowĐCPM\)
\(\frac{a}{b}\times4+\frac{1}{6}=\frac{17}{6}\)
\(\frac{a}{b}\times4=\frac{17}{6}-\frac{1}{6}\)
\(\frac{a}{b}\times4=\frac{16}{6}\)
\(\frac{a}{b}=\frac{16}{6}:4\)
\(\frac{a}{b}=\frac{2}{3}\)
a/b = 15/24
Bạn k mình nha
