$2 × 10^5+9×10^4+4× 10^3 + 8×10^2+6×10^1+3×10^0$
$294,863$ is the same thing as $200,000 + 90,000 +4,000+800+60+3$, which is $2 × 100,000 +9×10,000+4× 1,000 + 8×100+6×10+3×1$ $100,000$ is $10^5$$,10,000 is 10^4, 1,000 is 10^3, 100 is 10^2, 10 is 10^1 and 1 is 10^0, so the answer is$$\boxed{2 × 10^5+9×10^4+4× 10^3 + 8×10^2+6×10^1+3×10^0}$\$
