Tìm (x-1)^3= 1/8
Giải thích
\({\left( {x - 1} \right)^3} = \frac{1}{8}\)
\({\left( {x - 1} \right)^3} = {\left( {\frac{1}{2}} \right)^3}\)
\(x - 1 = \frac{1}{2}\)
\(x = 1 + \frac{1}{2}\)
\(x = \frac{3}{2}\)
\({\left( {x - 1} \right)^3} = \frac{1}{8}\)
\({\left( {x - 1} \right)^3} = {\left( {\frac{1}{2}} \right)^3}\)
\(x - 1 = \frac{1}{2}\)
\(x = 1 + \frac{1}{2}\)
\(x = \frac{3}{2}\)
