460=85.4=x+175 phần 5+30
Tìm x:
340=85.4=\(\frac{x+175}{5}\)+30
460+85.4=( x +200) ÷ 4
5x=125
5x = 125
x = 3
460 + 340 = (x + 200) : 4
800 = (x + 200) : 4
x + 200 = 800 : 4
x + 200 = 200
x = 200 - 200
x = 0
Hội con 🐄 chúc bạn học tốt!!!
460 + 340 = (x+200):4
8--=(x+200):4
x+200=800:4
x+200=200
x=200-200
x=0
5^x=125
x=3
\(460+85.4=\left(x+200\right):4\)
\(\Rightarrow\left(x+200\right):4=460+85.4\)
\(\Rightarrow\left(x+200\right):4=460+340\)
\(\Rightarrow\left(x+200\right):4=800\)
\(\Rightarrow\left(x+200\right)=800.4\)
\(\Rightarrow x+200=3200\)
\(x=3200-200\)
\(x=3000\)
Vậy \(x=3000\)
b) \(5^x=125\)
\(\Rightarrow5^x=5^3\)
Cơ số giống nhau suy ra số mũ giống nhau
\(\Rightarrow x=3\)
Vậy \(x=3\)
Chúc bạn học tốt !!!

460+85.4=(x+200).4
\(460+85.4=\)\(\left(x+200\right).4\)
\(460+340=\left(x+200\right).4\)
\(800\) \(=\left(x+200\right).4\)
\(\Rightarrow\left(x+200\right).4=800\)
\(\left(x+200\right)\) \(=800:4\)
\(x+200\) \(=200\)
\(x\) \(=200-200\)
\(x\) \(=0\)
Vậy x = 0
