The size of a certain cell is 2.5 × 10^–9 m. Another cell is 1.5 × 10^3 times larger. How large is the larger cell in scientific notation?
To determine how large the larger cell is in scientific notation, we need to multiply the size of the smaller cell by the scale factor 1.5 × 10^3.
2.5 × 10^–9 m × 1.5 × 10^3 = (2.5 × 1.5) × (10^–9 × 10^3) = 3.75 × 10^–6
Hence, the larger cell is 3.75 × 10^–6 m in scientific notation.
