Question

Express$3186000000$ In Standard Form

Answer 1

Expressing into standard form:

We can write $3186000000$ as $3186\times {10}^6$

$$\begin{gathered} 3186\times {10}^6 \\ =(3.186\times {10}^3)\times {10}^6 \\ =3.186\times {10}^{3+6}\left[\because a^m\times a^n=a^{m+n}\right] \\ =3.186\times {10}^9 \end{gathered}$$

Hence , the standard form is $3.186\times {10}^9$.
