Answer 1

1.25×10−5 by 2.5×10−3 millimeters

Answer 2

To convert the dimensions from meters to millimeters, we need to multiply them by 1,000 (since there are 1,000 millimeters in a meter).

The given dimensions are 1.25×10^(-8) meters wide and 2.5×10^(-6) meters long.

So, to convert the width to millimeters, we have:

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

Therefore, the width is 1.25×10^(-5) millimeters.

Similarly, to convert the length to millimeters, we have:

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

Therefore, the length is 2.5×10^(-3) millimeters.

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

Answer 3

To convert the dimensions from meters to millimeters, we need to multiply each dimension by 1,000 since 1 meter is equal to 1,000 millimeters.

The given dimensions are:

Width: 1.25 × 10^(-8) meters
Length: 2.5 × 10^(-6) meters

To convert the width to millimeters, we multiply it by 1,000:

1.25 × 10^(-8) meters * 1,000 = 1.25 × 10^(-5) millimeters

To convert the length to millimeters, we also multiply it by 1,000:

2.5 × 10^(-6) meters * 1,000 = 2.5 × 10^(-3) millimeters

Therefore, the dimensions in millimeters are 1.25 × 10^(-5) millimeters by 2.5 × 10^(-3) millimeters.

So the answer is:
1.25×10^(-5) by 2.5×10^(-3) millimeters.
