Question
Simplify the expression
622l4−1
Evaluate
l4×622−1
Solution
622l4−1
Show Solution

Find the roots
l1=−62246223,l2=62246223
Alternative Form
l1≈−0.200241,l2≈0.200241
Evaluate
l4×622−1
To find the roots of the expression,set the expression equal to 0
l4×622−1=0
Use the commutative property to reorder the terms
622l4−1=0
Move the constant to the right-hand side and change its sign
622l4=0+1
Removing 0 doesn't change the value,so remove it from the expression
622l4=1
Divide both sides
622622l4=6221
Divide the numbers
l4=6221
Take the root of both sides of the equation and remember to use both positive and negative roots
