Question

Fill in the blanks:

$5\times {10}^7+4\times {10}^6+2\times {10}^5+1\times {10}^4+3\times {10}^3+2\times {10}^2+1\times {10}^1+3\times {10}^0=...................$

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 -

$$\begin{gathered} 5\times {10}^7+4\times {10}^6+2\times {10}^5+1\times {10}^4+3\times {10}^3+2\times {10}^2+1\times {10}^1+3\times {10}^0 \\ =5\times 10000000+4\times 1000000+2\times 100000+1\times 10000+3\times 1000+2\times 100+1\times 10+3\times 1 \\ =50000000+4000000+200000+10000+3000+200+10+3 \\ =54213213 \end{gathered}$$

Hence, the value is $54213213$.
