Question

how many significant figures are there in the number 3,400?

Explanation:

Step1: Apply significant figures rules

Non - zero digits are always significant. In \(3400\), the digits \(3\) and \(4\) are non - zero. Trailing zeros in a number without a decimal point may or may not be significant. Here, \(3400\) can be thought of as \(3.4\times10^{3}\) (scientific notation), and the zeros are just placeholders.

Answer:

\(2\)
