Ta có: \(x+18954\div3^5=4.5^3\)
\(\Leftrightarrow x+18954\div243=4.125\)
\(\Leftrightarrow x+78=500\)
\(\Rightarrow x=422\)
x + 18954 : 35 = 4 . 53
=> x + 18954 : 243 = 4 . 125
=> x + 78 = 500
=> x = 422
Vậy x = 422
\(x+18954:3^5=4\cdot5^3\)
\(x+18954\) \(:243=4.125\)
\(x+78=500\)
\(\Rightarrow x=422\)
