Question

Which expression is equivalent to the expression shown in the picture?

Answer 1

Given:

The expression is

$(2.5\times10^{-6})(7.3\times10^{-2})$

Required:

To find the equivalent expression to the given expression.

Explanation:

The expression is

$(2.5\cdot10^{-6})(7.3\cdot10^{-2})$

Solve by multiplication the given expression.

$\begin{gathered} (2.5\cdot10^{-6})(7.3\cdot10^{-2})=(2.5\times7.3)\times10^{-6-2} \\ (2.5\cdot10^{-6})(7.3\cdot10^{-2})=18.25\times10^{-8} \\ (2.5\cdot10^{-6})(7.3\cdot10^{-2})=1.825\times10^{-7} \end{gathered}$

Final Answer:

The second option is the correct answer.
