Solve the equation
x1=0,x2=2
Evaluate
22x×8=x4
Reduce the fraction
More Steps
Evaluate
22x×8
Multiply the terms
216x
Reduce the fraction
8x
8x=x4
Move the expression to the left side
8x−x4=0
Factor the expression
x(8−x3)=0
Separate the equation into 2 possible cases
x=08−x3=0
Solve the equation
More Steps
Evaluate
8−x3=0
Move the constant to the right-hand side and change its sign
−x3=0−8
Removing 0 doesn't change the value,so remove it from the expression
−x3=−8
Change the signs on both sides of the equation
x3=8
Take the 3-th root on both sides of the equation
3x3=38
