Question

I am needing help on how to this step by step please

Answer 1

The pattern will look like this:

`\begin{gathered} (20)/(10)=2=2(10)^0 \\ (20)/(10^2)=(2)/(10)=2(10)^(-1) \\ (20)/(10^3)=(2)/(100)=2(10)^(-2) \\ (20)/(10^4)=(2)/(1000)=2(10)^(-3) \end{gathered}`

The next number will have index of 10 as -4,-5 and so on.
