Question

how do you write 25.4 millimeters in scientific notation

Answer 1

25.4 millimeters can be written as: 2.54E1 mm.

Explanation:

25.4 millimeters in scientific notation can be written as: 2.54E1 mm.

We know that E means 10 to the power of the number that comes directly after it.

25.4 mm can also be written as 2.54E-2 m, if you want it in meters; since 25.4 mm = 0.0254 meters.

Answer 2

2.54x10 to the 1st power because you take the first number you see to the left, place the decimal behind it, write the other numbers behind it (don't include 0s unless the 0 has a number above 0), multiply by 10, and to figure out the exponet, you just count how many spaces the decimal moves. If the decimal moves to the right then the exponent is positive, of you move it to the left then the exponet is negative.
