Question

(2.4 x 10 ^- 4) (1.6 x 10^-5)

Answer 1

Answer:$3.84\text{ }\times10^{-9}$Explanations:

The given expression is:

$(2.4\text{ }\times10^{-4})(1.6\text{ }\times10^{-5})$

This can be simplified as:

$2.4\text{ }\times\text{ 1.6 }\times10^{-4}\times10^{-5}$$\text{Note that a}^b\times a^c=a^{b+c}$

Therefore, the above expression can be further simplified as:

$\begin{gathered} 3.84\text{ }\times10^{-4-5} \\ 3.84\text{ }\times10^{-9} \end{gathered}$
