Answer 2

Step-by-step explanation:

$\blue{\bold{\underline{\underline{Question}}}}$

If a=xy^p-1, b=xy^q-1, and c=xy^r-1 , then let ua show that a^q-r b^r-p c^p-q=1.

$\blue{\bold{\underline{\underline{Answer}}}}$

$\blue{\bold{\underline{\underline{Given}}}}$

$a = {xy}^{p - 1}$

$b = {xy}^{q - 1}$

$c = {xy}^{r - 1}$

$lhs = = {a}^{q - r} {b}^{r - p} {c}^{p - q}$

$= ( {xy ^{p - 1} })^{q - r} ( {xy}^{q - 1} )^{r - p} ( {xy}^{r - 1} )^{p - q}$

$= {x}^{q - r - p + p - q} {y}^{qp + r - q - pr + qr + p - qp - r + pr + q - p - q}$

$= {x}^{0} {y}^{0}$

$= 1$

therefore,

hence proved.....
