Answer 1

Answer:

$44$

Explanation:

Here, we want to get the product of the multiplication

The task here is to write the answer in the correct number of significant figures

We have to write the answer in the lowest number of significant figures

The first number has 4 significant figures while the second has two

This means our answer would be in 2 significant figures

Thus, we have the product as:

$19.10\text{ }\times\text{ 2.3 = 43.93}$

In two significant figures, we have this as 44
