Question

Expand 2020.297, expressing each value as the product of a single-digit integer and an integer power of 10.

Answer 1

2020.297 is equal to

2000+20+0.2+0.09+0.007

Expressing those values as the product of a single digit integer and an integer power of 10 we have:

`\begin{gathered} 2000=2\cdot10^3 \\ 20=2\cdot10^1 \\ 0.2=2\cdot10^(-1) \\ 0.09=9\cdot10^(-2) \\ 0.007=7\cdot10^(-3) \end{gathered}`

Re write the addition

`2020.297=2\cdot10^3+2\cdot10^1+2\cdot10^(-1)+9\cdot10^(-2)+7\cdot10^(-3)`
