Let a, b, c, and x be elements of a group G. In each of the following, solve for x in terms of a, b, and c.
Solution
Let a,b,c, and x be elements of a group G
(xax)3 =bx and x2a = (xa)-1
(xax)3 =bx
((xax)3)-2 =(bx)-2
xax = x-2 b-2
Multiply left by x
x(xax) = x(x-2 b-2)
(xxa)x =( xx-2 ) b-2
(a1x1)x = (x1)b2 from x2a = (xa)-1 = a-1 x-1 and xx-2 = (xx-1)x-1
a1(x1x)=(x1)b2
a1 = (x1)b2
xa1=b2
x= b-2 a
