`#3107.101107`
\(3\left(x-32\right)-7=23\cdot5-50\)
\(\Rightarrow3\left(x-32\right)-7=115-50\)
\(\Rightarrow3\left(x-32\right)-7=65\)
\(\Rightarrow3\left(x-32\right)=65+7\)
\(\Rightarrow3\left(x-32\right)=72\)
\(\Rightarrow x-32=72\div3\)
\(\Rightarrow x-32=24\)
\(\Rightarrow x=24+32\)
\(\Rightarrow x=56\)
Vậy, `x = 56.`
\(3\left(x-32\right)-7=23.5-50\)
\(3\left(x-32\right)-7=115-50\)
\(3\left(x-32\right)-7=65\)
\(3\left(x-32\right)=65+7\)
\(3\left(x-32\right)=72\)
\(x-32=72:3\)
\(x-32=24\)
\(x=24+32\)
\(x=56\)

\(\left(7x-11\right)^3=2^5.5^2+2.10^2\)
\(\Rightarrow\left(7x-11\right)^3=32.25+2.100\)
\(\Rightarrow\left(7x-11\right)^3=800+200\)
\(\Rightarrow\left(7x-11\right)^3=1000\)
\(\Rightarrow\left(7x-11\right)^3=10^3\)
\(\Rightarrow7x-11=10\)
\(\Rightarrow7x=21\)
\(\Rightarrow x=3\)
(7\(x\) - 11)3 = 25.52 + 2.102
(7\(x\) - 11)3 = 1000
(7\(x\) - 11)3 = 103
7\(x\) - 11 = 10
7\(x\) = 10 + 11
7\(x\) = 21
\(x\) = 21:7
\(x\) = 3
