ta có: \(\frac{31+32+35}{34}=\frac{31}{34}+\frac{32}{34}+\frac{35}{34}.\)
mà \(\frac{31}{32}>\frac{31}{34};\frac{32}{33}>\frac{32}{34}\)
\(\Rightarrow\frac{31}{32}+\frac{32}{33}+\frac{35}{34}>\frac{31}{34}+\frac{32}{34}+\frac{35}{34}=\frac{31+32+35}{34}\)
\(\left(190-2.x\right):35+32=16\)
\(=>\left(190-2x\right):35=-16\)
\(=>190-2x=-560\)
\(=>2x=750\)
\(=>x=375\)
Ủng hộ nha các bạn
\(x=255-32\times4=255-12=127\)
\(78+127+35=205+35=240\)

= > a : 35 = 5,6 : 32
=> a : 35 = 0,175
=> a = 0,175 * 35
=> a = 6,125
\(\frac{14^{16}\times21^{32}\times35^{48}}{10^{16}\times35^{32}\times7^{96}}\)
\(=\frac{\left(2\times7\right)^{16}\times\left(3\times7\right)^{32}\times\left(5\times7\right)^{48}}{\left(2\times5\right)^{16}\times\left(5\times7\right)^{32}\times7^{96}}\)
\(=\frac{2^{16}\times7^{16}\times3^{32}\times7^{32}\times5^{48}\times7^{48}}{2^{16}\times5^{16}\times5^{32}\times7^{32}\times7^{96}}=\frac{2^{16}+7^{96}+3^{32}+5^{48}}{2^{16}\times5^{48}\times7^{32}\times7^{96}}\)
\(=\frac{3^{32}}{7^{32}}=\left(\frac{3}{7}\right)^{32}\)
(190 - 2 x X) : 35 + 32 = 16
(190 - 2x) : 35 = 16 - 32
(190 - 2x) : 35 = -16
190 - 2x = -16 x 35
190 - 2x = -560
-2x = -560 - 190
-2x = -750
\(x=\frac{-750}{-2}=375\)
