Step-by-step explanation:
Given that there are <span>6 boys and 6 girls in a birthday party, the number of different arrangements of</span><span> first, second, and third is given by:

</span>
The greatest counting number that divides 17, 25 and 41 and leaves the same remainder in each case is 8
RHS-
(x+y)(x²-xy+y²)
=x(x²-xy+y²)+y(x²-xy+y²)
=x³-x²y+xy²+x²y-xy²+y³
(CANCEL THE POSSIBLE TERMS)
=x³+y³
=LHS
therefore verified
