ta có :
\(\left(25-2x\right)^3:5=2^4+3^2=16+9=25\)
hay \(\left(25-2x\right)^3=25\times5=125=5^3\Leftrightarrow25-2x=5\Leftrightarrow2x=20\)
\(\Leftrightarrow x=10\)
( 25 - 2x )3 : 5 - 24 = 32
=> ( 25 - 2x )3 : 5 - 16 = 9
=> ( 25 - 2x )3 : 5 = 25
=> ( 25 - 2x )3 = 125
=> ( 25 - 2x )3 = 53
=> 25 - 2x = 5
=> 2x = 20
=> x = 10
\(\left(25-2x\right)^3:5-2^4=3^2\)
\(\left(25-2x\right)^3:5-16=9\)
\(\left(25-2x\right)^3:5=9+16\)
\(\left(25-2x\right)^3:5=25\)
\(\left(25-2x\right)^3=25.5\)
\(\left(25-2x\right)^3=125\)
\(\left(25-2x\right)^3=5^3\)
\(\Rightarrow25-2x=5\)
\(2x=25-5\)
\(2x=20\)
\(x=20:2\)
\(x=10\)
