1. MEASUREMENT There are about 25.4 millimeters in one inch. Write this number in scientific notation.

The number 25.4 can be expressed in scientific notation as 2.54 x 10^1. This means that you take the first significant digit (2.54) and multiply it by 10 raised to the power of the number of places you moved the decimal point (which is 1 place to the left to get 2.54). So voilà, scientific notation at its finest! Now, if you're measuring things often, you'll find that understanding conversions like millimeters to inches is handy! For example, if you're crafting furniture or designing a space, knowing how many inches fit into a millimeter can help avoid those pesky errors when you're precision measuring. Just remember, converting back and forth can save you heaps of time and potential frustration. Happy measuring!
