(2.4 x 10-9) (4.0 x 1023) = _____

$$\mathbf{9.6*10^{14}}$$

\mathbf{9.6*10^{14}}

 

I haven't seen that bold face command before (I am assuming that is what it stands for)

I'll record that in our Latex thread. 

Thanks Aziz.

This is how you can do your question without a calculator.

$$(2.4 \times 10^{-9}) (4.0 \times 10^{23}) \\\\
=2.4\times4 \times 10^{-9}\times 10^{23}\\\\
=2.4\times4 \times 10^{-9}\times 10^{23}\\\\
=9.2\times 10^{-9+23}\\\\
=9.2\times 10^{14}\\\\$$

.

(2.4 x 10^-9) (4.0 x 10^23) 

= (2.4*10^-9)*(4.0* 10^23)

= 960000000000000

= $$\mathbf{9.6*10^{14}}.$$
