Answer
$8 × 10^4$+ $3×10^3+4× 10^2 + 0 × 10^1 + 1 × 10^0$
Work Step by Step
$83,401$ is the same thing as $80,000 + 3,000+400+1$, which is
$8×10,000+3× 1,000 + 4×100+0×10+1×1$
$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
$$\boxed{8×10^4+3× 10^3 + 4×10^2+0×10^1+1×10^0}$$
