Question
Simplify the expression
122l5−1
Evaluate
l5×122−1
Solution
122l5−1
Show Solution

Find the roots
l=12251224
Alternative Form
l≈0.382585
Evaluate
l5×122−1
To find the roots of the expression,set the expression equal to 0
l5×122−1=0
Use the commutative property to reorder the terms
122l5−1=0
Move the constant to the right-hand side and change its sign
122l5=0+1
Removing 0 doesn't change the value,so remove it from the expression
122l5=1
Divide both sides
122122l5=1221
Divide the numbers
l5=1221
Take the 5-th root on both sides of the equation
5l5=51221
Calculate
l=51221
