[QUOTE="Robb, post: 6167490, member: 571890"] [B]Homework Statement:[/B] Let ##q \geq 2## be an integer. Let ##n = (d_k d_{k-1} \dots d_1 )_(q)## be a q-ary representation of n. Prove that ##nq = (d_k d_{k-1} \dots d_1 0)_(q)##. [B]Relevant Equations:[/B] as above for n and nq. ##nq = q(d_1 + d_2 q + d_3 q^2 + \dots + d_k q^{k-1})## ##= d_1 q + d_2 q^2 + d_3 q^3 + \dots + d_k q^k## ##= d_k d_{k-1} \dots d_1 0## Can someone please explain how to get from line two to line three. This is instructors solution and not sure I understand. Thanks! [/QUOTE]
