Question

Fill in the blanks:

$3867=3\times {10}^3+8\times {10}^2+..............+7\times {10}^0$

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 -

$$\begin{gathered} 3867=3000+800+60+7 \\ =3\times 1000+8\times 100+6\times 10+7\times 1 \\ =3\times {10}^3+8\times {10}^2+6\times {10}^1+7\times {10}^0 \end{gathered}$$

Hence, the missing term is $6\times {10}^1$.
