Difficulty: Easy
Correct Answer: 3,300
Explanation:
Introduction / Context:Scientific notation expresses numbers compactly as a coefficient times a power of ten. Converting back and forth prevents place-value mistakes when entering data into calculators or spreadsheets.
Given Data / Assumptions:
Concept / Approach:Multiply the coefficient 3.3 by 1000. Moving the decimal right expands the value by three orders of magnitude, preserving significant digits (here, two significant figures: 3.3).
Step-by-Step Solution:
Write 3.3 × 1000.Compute: 3.3 × 1000 = 3300.Format with thousands separator → 3,300.Verification / Alternative check:Place-value shift: 3.3 → 33.0 (10^1) → 330.0 (10^2) → 3300.0 (10^3). The result is 3,300 exactly.
