Given Exp.= `x^((b - c)(b + c - a))` . `x^((c - a)(c + a - b))`. `x^((a - b)(a + b - c))`
=`x^((b - c) (b + c) -a (b - c))` . `x^((c - a) (c + a) - b(c -a))` . `x^((a - b) (a + b) - (a - b))`
=`x^((b^2 -c^2 + c^2 -a^2 + a^2 - b^2))` . `x^ - a(b - c) - b(c - a) -c(a - b)` =`(x^0 xx x^0)` = 1 x 1 = 1.
