Answer» (x^b/x^c)^[b + c - a] * (x^c/x^a)^[c + a - b] * (x^a/x^b)^[a + b - c] = x^(b-c)(b + c - a) * x^(c-a)(c + a - b) * x^(a-b)(a + b - c) = x^[b^2 + bc - ab - bc - c^2 + ac] * x^[c^2 + ac - bc - ac - a^2 + ab] * x^[a^2 + ab - ac - ab - b^2 + bc] = x^[b^2 - b^2 + c^2 - c^2 + a^2 - a^2 + ac - ac + ab - ab + bc - bc] = x^0 = 1

Answer»

(x^b/x^c)^[b + c - a] * (x^c/x^a)^[c + a - b] * (x^a/x^b)^[a + b - c]

= x^(b-c)(b + c - a) * x^(c-a)(c + a - b) * x^(a-b)(a + b - c)

= x^[b^2 + bc - ab - bc - c^2 + ac] * x^[c^2 + ac - bc - ac - a^2 + ab] * x^[a^2 + ab - ac - ab - b^2 + bc]

= x^[b^2 - b^2 + c^2 - c^2 + a^2 - a^2 + ac - ac + ab - ab + bc - bc]

= x^0

= 1
