Question

To the correct number of significant figures: (2.233 x 10-2) + (3.2 x 10-3) =Group of answer choices0.02552.6 x 10-2

Answer 1

Given the expression:

`(2.233\cdot10^(-2))+(3.2\cdot10^(-3))=`

The answer will be as follows:

`\begin{gathered} 2.233\cdot10^(-2)=0.02233 \\ 3.2\cdot10^(-3)=0.0032 \\ \\ (2.233\cdot10^(-2))+(3.2\cdot10^(-3))=0.02233+0.0032=0.02553 \end{gathered}`

So, the answer will be 0.0255
