Question
Simplify the expression
422l5−1
Evaluate
l5×422−1
Solution
422l5−1
Show Solution

Find the roots
l=42254224
Alternative Form
l≈0.298495
Evaluate
l5×422−1
To find the roots of the expression,set the expression equal to 0
l5×422−1=0
Use the commutative property to reorder the terms
422l5−1=0
Move the constant to the right-hand side and change its sign
422l5=0+1
Removing 0 doesn't change the value,so remove it from the expression
422l5=1
Divide both sides
422422l5=4221
Divide the numbers
l5=4221
Take the 5-th root on both sides of the equation
5l5=54221
Calculate
l=54221
