Question

Brianna broke a cell sample into 12 batches, each weighing 8.7 x 10-5much did the original sample weigh? Use scientific notation to express your answer.

Answer 1

`104.4\cdot10^(-5)`

Step-by-step explanation

to figure out this we need to use a multiplication

so

Total wigth= number of batches * unit weight

replacing

`\begin{gathered} \text{total weigh=12}\cdot(8.7\cdot10^(-5))=104.4\cdot10^(-5) \\ \text{so,the answer is} \\ 104.4\cdot10^(-5) \end{gathered}`

I hope this helps you
