Kendra finds the dimensions of a sticky note. She uses a meter stick to determine that the dimensions are 1.25×10^−8 meters wide by 2.5×10^−6 meters long. Use scientific notation to write the dimensions in millimeters.

Question

Note: 1 meter is equal to 1,000 millimeters.

Answer 1

To convert the dimensions from meters to millimeters, we need to multiply by 1,000.

Width: 1.25 × 10^(-8) meters * 1,000 millimeters/1 meter = 1.25 × 10^(-8) × 1,000 = 1.25 × 10^(-8+3) = 1.25 × 10^(-5) millimeters

Length: 2.5 × 10^(-6) meters * 1,000 millimeters/1 meter = 2.5 × 10^(-6) × 1,000 = 2.5 × 10^(-6+3) = 2.5 × 10^(-3) millimeters

Therefore, the dimensions of the sticky note in millimeters are 1.25 × 10^(-5) millimeters wide by 2.5 × 10^(-3) millimeters long.
