Question
Solve the equation
x1=−36,x2=36
Alternative Form
x1≈−1.817121,x2≈1.817121
Evaluate
∣x3∣12=2
Find the domain
More Steps

Evaluate
x3=0
Rewrite the expression
x3=0
The only way a power can not be 0 is when the base not equals 0
x=0
∣x3∣12=2,x=0
Cross multiply
12=x3×2
Simplify the equation
12=2x3
Rewrite the expression
2×6=2x3
Evaluate
6=x3
Swap the sides of the equation
x3=6
Separate the equation into 2 possible cases
x3=6x3=−6
Solve the equation for x
More Steps

Evaluate
x3=6
Take the 3-th root on both sides of the equation
3x3=36
Calculate
x=36
x=36x3=−6
Solve the equation for x
More Steps

Evaluate
x3=−6
Take the 3-th root on both sides of the equation
3x3=3−6
Calculate
x=3−6
An odd root of a negative radicand is always a negative
