5.x=53
5.x=125
x=125:5
x=25
** mk nha
\(5.x=5^3\)
\(\Leftrightarrow5.x=5.5.5\)
\(\Rightarrow x=\left(5.5.5\right):5\)
\(\Rightarrow x=5.5=25\)
\(5.x=5^3\)
\(5.x=125\)
\(x=125:5\)
\(x=25\)
k mik nha bn. thank you
5.x = 5^3
5.x = 125
x = 125 : 5
x = 25
5 . x = 53
5 . x = 125
x = 125 : 5
x = 25
5 . x = 53
5 . x = 125
<=> x = 125 : 5
<=> x = 25.
x . 5 = 53
x . 5 = 125
x = 125 : 5
x = 25
5 . x = 53
5 . x = 125
x = 125 : 5
x = 25
x . 5 = 53
x . 5 = 125
x = 125 : 5
x = 25
