Solve for k.
Multiply each term by k and simplify.
Multiply each term in 2Wk=L2 by k.
2Wk⋅k=L2⋅k
Cancel the common factor of k.
Cancel the common factor.
2Wk⋅k=L2⋅k
Rewrite the expression.
2W=L2⋅k
2W=L2k
2W=L2k
Rewrite the equation as L2k=2W.
L2k=2W
Divide each term by L2 and simplify.
Divide each term in L2k=2W by L2.
L2kL2=2WL2
Cancel the common factor of L2.
Cancel the common factor.
L2kL2=2WL2
Divide k by 1.
k=2WL2
k=2WL2
k=2WL2
k=2WL2
Solve for k L = square root of (2W)/k
