x^4+73=154
=x^4=154-73
x^4=81
=x^4=3^4
x=3
x4 + 73 = 154
x4 = 154 - 73
x4 = 81
x4 = 34
x = 3
x4+73=154
<=> x4=154-73
<=> x4=81
<=> x=3 hoặc x=-3
x4 + 73 = 154
x4 = 154 - 72
x4 = 81
x4 = 34
=> x = 3
\(x^4+73=154\)
\(x^4=154-73\)
\(x^4=81\)
\(x^4=3^4\)
\(\Rightarrow x=3\)
\(x^4+73=154\)
\(x^4=154-73\)
\(x^4=81\)
\(x^4=4^4\)
\(x=4\)
Vậy x = 4
Ủng hộ mk 1 k nha , Luyện nè
x4 + 73 = 154
x4 = 154 - 73
x4 = 81
x4 = 34
=> x = 3
Vậy x = 3
x4 + 73 = 154
x4 = 154 - 73
x4 = 81
x4 = 34
Vậy x4 bằng 34
\(x^4=154-73\)
\(x^4=81\)
\(x^4=3^4\)
\(\Rightarrow x=3\)
Vậy x = 3
x^4 = 154 - 73 x^4 = 81 <=> x^4 = 3^4 =>x = 3 Vậy x = 3.Đúng thì k để tôi bt.Ok???
\(^{x^4+73=154\Rightarrow x^4=81\Rightarrow x^4=3^4\Rightarrow x=4}\)
x4+73=154
x4 =154-73
x4 =81
x4 =34
suy ra x=3
\(x^4+73=154\)
\(x^4=154-73\)
\(x^4=81\)
\(x^4=3^4\)
\(\Rightarrow x=3\)
vậy \(x=3\)
x4 + 73 = 154
=> x4 = 154 - 73
=> x4 = 81
mà x4 = 34
vậy x = 3
