FALSE. This is a tricky concept that often appears in ECZ exams. The number 5000 written without a decimal point is ambiguous. Trailing zeros in whole numbers (zeros at the end with no decimal point) are NOT automatically significant because we don't know if they're placeholders or measured values. 5000 could represent: 1 s.f. (approximately 5 thousand), 2 s.f. (about 50 hundred), 3 s.f., or 4 s.f. depending on the precision of the measurement. To show that all zeros are significant, we must write it as 5000. (with a decimal point) or use scientific notation like \(5.000 \times 10^3\). Without this indication, assume only the non-zero digits are significant, giving us 1 significant figure.
