Question
Simplify the expression
611l4−1
Evaluate
l4×611−1
Solution
611l4−1
Show Solution

Find the roots
l1=−61146113,l2=61146113
Alternative Form
l1≈−0.201136,l2≈0.201136
Evaluate
l4×611−1
To find the roots of the expression,set the expression equal to 0
l4×611−1=0
Use the commutative property to reorder the terms
611l4−1=0
Move the constant to the right-hand side and change its sign
611l4=0+1
Removing 0 doesn't change the value,so remove it from the expression
611l4=1
Divide both sides
611611l4=6111
Divide the numbers
l4=6111
Take the root of both sides of the equation and remember to use both positive and negative roots
