Question
Simplify the expression
164l3−9
Evaluate
l3×164−9
Solution
164l3−9
Show Solution

Find the roots
l=82330258
Alternative Form
l≈0.380014
Evaluate
l3×164−9
To find the roots of the expression,set the expression equal to 0
l3×164−9=0
Use the commutative property to reorder the terms
164l3−9=0
Move the constant to the right-hand side and change its sign
164l3=0+9
Removing 0 doesn't change the value,so remove it from the expression
164l3=9
Divide both sides
164164l3=1649
Divide the numbers
l3=1649
Take the 3-th root on both sides of the equation
3l3=31649
Calculate
l=31649
