Question
Simplify the expression
213l3−1
Evaluate
l3×213−1
Solution
213l3−1
Show Solution

Find the roots
l=213345369
Alternative Form
l≈0.167445
Evaluate
l3×213−1
To find the roots of the expression,set the expression equal to 0
l3×213−1=0
Use the commutative property to reorder the terms
213l3−1=0
Move the constant to the right-hand side and change its sign
213l3=0+1
Removing 0 doesn't change the value,so remove it from the expression
213l3=1
Divide both sides
213213l3=2131
Divide the numbers
l3=2131
Take the 3-th root on both sides of the equation
3l3=32131
Calculate
l=32131
