Question
Solve the equation
x1=0,x2=81
Alternative Form
x1=0,x2=0.125
Evaluate
x4=4x5×2
Multiply the numbers
x4=8x5
Move the expression to the left side
x4−8x5=0
Factor the expression
x4(1−8x)=0
Separate the equation into 2 possible cases
x4=01−8x=0
The only way a power can be 0 is when the base equals 0
x=01−8x=0
Solve the equation
More Steps
Evaluate
1−8x=0
Move the constant to the right-hand side and change its sign
−8x=0−1
Removing 0 doesn't change the value,so remove it from the expression
−8x=−1
Change the signs on both sides of the equation
8x=1
Divide both sides
88x=81
Divide the numbers
x=81
x=0x=81
Solution
x1=0,x2=81
