Step 1: Write the number in words

Given number, $100000098$

$$\begin{gathered} \mathrm{TC}\mathrm{C}\mathrm{TL}\mathrm{L}\mathrm{TTh}\mathrm{Th}\mathrm{H}\mathrm{T}\hspace{0.17em}\mathrm{O} \\ 100000098 \end{gathered}$$

So, the given number is ten crore ninety-eight.

Step 2: Write the number in expanded form

$$\begin{gathered} \mathrm{TC}\mathrm{C}\mathrm{TL}\mathrm{L}\mathrm{TTh}\mathrm{Th}\mathrm{H}\mathrm{T}\hspace{0.17em}\mathrm{O} \\ 100000098 \\ \Rightarrow 1\times 100000000+0\times 10000000+0\times 1000000+0\times 100000+0\times 10000+0\times 1000+0\times 100+9\times 10+8 \\ =100000000+90+8 \end{gathered}$$

Hence, the given number in words is ten crore ninety-eight

and expanded form of the given number is $100000000+90+8$.
