Question

Very large numbers can be expressed in standard form by using __________. Fill in the blank to make the statement true.

Answer 1

Let us taken an example

Take a number $234000000$.

$\begin{array}{rcl}234000000& =& 234\times 1000000\\ & =& 2.34\times 100\times {10}^6\\ & =& 2.34\times {10}^2\times {10}^6\\ & =& 2.34\times {10}^{2+6}\\ & =& 2.34\times {10}^8\end{array}$

Hence, we observe that very large numbers can be expressed in standard form by using positive exponents.
