x5−3x4=0
Factor the expression
x4(x−3)=0
Separate the equation into 2 possible cases
x4=0x−3=0
The only way a power can be 0 is when the base equals 0
x=0x−3=0
Solve the equation

Evaluate
x−3=0
Move the constant to the right-hand side and change its sign
x=0+3
Removing 0 doesn't change the value,so remove it from the expression
x=3
x=0x=3
Solution
x1=0,x2=3
