(x^a ÷ x^b)^(a²+ab+b²) * (x^b ÷x^c)^(b²+bc+c²) * (x^c÷x^a)^(c²+ca+a²) | Indices - Simply | SciPiPupil

Question: Simplify: $(x^a ÷ x^b)^{a²+ab+b²} ×$$(x^b÷x^c)^{b²+bc+c²} ×$$(x^c ÷x^a)^{c²+ca+a²}$

Solution:

Given,

$= (x^a ÷ x^b)^{a²+ab+b²} × (x^b÷x^c)^{b²+bc+c²} ×(x^c ÷x^a)^{c²+ca+a²}$

$= (x^{a-b})^{a²+ab+b²} × (x^{b-c})^{b²+bc+c²} ×(x^{c-a})^{c²+ca+a²}$

$= x^{(a-b)(a²+ab+b²)} × x^{(b-c)(b²+bc+c²)} × x^{(c-a)(c²+ca+a²)}$

$= x^{a³ -b³} × x^{b³ -c³} × x^{c³-a³}$

$= x^{a³ -b³+(b³-c³) +(c³-a³)}$

$= x^{a³-b³+b³-c³+c³-a³}$

$= x^0$

$= 1$

= Answer
