Question

Find the number from each of the following expanded forms: ${(9\times 10)}^5+{(2\times 10)}^2+{(3\times 10)}^1$.

Answer 1

Compute the required value:

The number can be found as

$$\begin{gathered} {(9\times 10)}^5+{(2\times 10)}^2+{(3\times 10)}^1 \\ \Rightarrow {\left(90\right)}^5+{\left(20\right)}^2+\left(30\right) \\ \Rightarrow 5904900000+400+30 \\ \Rightarrow 5904900430 \end{gathered}$$

Hence, the number from the expanded form ${(9\times 10)}^5+{(2\times 10)}^2+{(3\times 10)}^1$ is $5904900430$.
