Question

What is 0.02349 written in standard form to 3 significant figures

Answer 1

Let's cancel out from left to right

$\\ \sf\Rrightarrow 0.02349$

$\\ \sf\Rrightarrow 0.0235\times 10^{-1}$

$\\ \sf\Rrightarrow 2.35\times 10^{-3}$

Option C is correct

Answer 2

Answer: The answer is (B)

Explanation: The answer is (B) because, there are 2 zeros so that means that there would have to be a 2 behind the 10 and then there is 2,3,4,and 9. We take out the 9 and use the other numbers, bring over the decimal and now you have $2.34 x 10^{2}$ .
