In the expanded form, we can write 55,000 as

\begin{aligned}

&5 \times \text { Ten thousand }+5 \times \text { Thousand }+0 \times \text { Hundred }+0 \times \text { Ten }+0 \times \text { One } \\

&=5 \times 10000+5 \times 1000+0 \times 100+0 \times 10+0 \times 1 \\

&=55000 \\

&=\text { Fifty Five thousand }

\end{aligned}
