460+85.4=( x +200) ÷ 4

5^x=125

Answer 1

[๖²⁴ʱんuﾘ ｲú❄✎﹏]

\(460+85.4=\left(x+200\right):2\)

\(460+340=\left(x+200\right):4\)

\(800=\left(x+200\right):4\)

\(\left(x+200\right):4=800\)

\(x+200=800.4\)

\(x+200=3200\)

\(x=3200-200\)

\(x=3000\)

\(5^x=125\)

\(5^x=5^3\)

Vì \(5=5\)

\(\Rightarrow x=3\)

Answer 2

[Bò Vinamilk 3 không (Hội Con 🐄)]

5^x = 125

x = 3

460 + 340 = (x + 200) : 4

800 = (x + 200) : 4

x + 200 = 800 : 4

x + 200 = 200

x = 200 - 200

x = 0
