Question

Fill in the blanks:

$.................=6.989\times {10}^4$

Answer 1

Whenever we multiply any decimal number with $10,100,1000,........$ then the decimal point $(.)$ shifts towards right hand side depending on the number of $"0"$ present in the multiplicand.

$$\begin{gathered} 6.989\times {10}^4=6.989\times 10000 \\ =69890 \end{gathered}$$

Hence, the correct answer is $69890$
