Chapter SH, Problem 9.14E

To determine

Find the expanded form of the given number using power of $10$ .

Answer to Problem 9.14E

The expanded form of the given number is $7\left({10}^3\right)+1\left({10}^2\right)+2\left({10}^1\right)+5\left({10}^0\right)$ .

Explanation of Solution

Given:

The given number is $7125$ .

Calculation:

The expanded form of the number is

  $\begin{array}{l}7125\\ =7\times 1000+1\times 100+2\times 10+5\times 1\end{array}$

The expanded form of the number using power of $10$ .

  $=7\left({10}^3\right)+1\left({10}^2\right)+2\left({10}^1\right)+5\left({10}^0\right)$

Hence the expanded form of the given number is $7\left({10}^3\right)+1\left({10}^2\right)+2\left({10}^1\right)+5\left({10}^0\right)$ .
