Easy method (X/6)(x/6)=(6/x)(6/X) Get x/6 commen fromLHS and 6/x from RHS WE get X/6(1×1)=6/x(1×1). X/6=6/x By cross multiplication We get X×X=36 Taking square root of both sides X=6 If we put the value of x in the given equation,it will satisfied
I learned complex numbers and DeMoivres Formula in 11th grade high school math in New York in 1970. Rewrite as X^4 = 6^4 X = 6A, where A is one of the four fourth roots of unity; A = +- 1, A = +- i
Easy method
(X/6)(x/6)=(6/x)(6/X)
Get x/6 commen fromLHS
and 6/x from RHS
WE get
X/6(1×1)=6/x(1×1).
X/6=6/x
By cross multiplication
We get
X×X=36
Taking square root of both sides
X=6
If we put the value of x in the given equation,it will satisfied
