Question

Fill in the blanks:

$7\times {10}^5+7\times {10}^4+2\times {10}^3+3\times {10}^2+4\times {10}^1+7\times {10}^0=...................$

Answer 1

Whenever we write the expanded form of any number, we write in the form of a summation of the place values of each digit.

Let's write the expanded form of number to normal form -

$$\begin{gathered} 7\times {10}^5+7\times {10}^4+2\times {10}^3+3\times {10}^2+4\times {10}^1+7\times {10}^0 \\ =7\times 100000+7\times 10000+2\times 1000+3\times 100+4\times 10+7\times 1 \\ =700000+70000+2000+300+40+7 \\ =772347 \end{gathered}$$

Hence, the missing term is $772347$.
