Question

Write 0.452 in scientific notation

Answer 1

Answer:

4.52*10^-1

Step-by-step explanation:

0.452

Scientific notation is in the form a* 10^b

a must be between 1 and less than 10

move the decimal 1 place to the right

04.52

Since we moved the decimal 1 place to the right b is 1 and right means negative

4.52*10^-1

Answer 2

Step-by-step explanation: To write 0.452 in scientific notation, we first write a decimal point in the number so that there is only one digit to the left of the decimal point.

So here we have 4.52. Notice that the zeros don't count as digits to the left of the decimal point. Next, count the number of places that we would need to move the decimal point in order to get back to the original number.

Here, we would need to move the decimal point one place to the left in order to get back to the original number, 0.452.

Now, scientific notation is written properly when it is composed of a whole number or decimal between 1 and 10 and times a power of 10,

This means that we need to multiply 4.52 times $10^{-1}$.

Notice that our exponent is negative.

That's because we needed to move the decimal point to the left to get back to the original number.

So 0.452 can be written in scientific notation as  $4.52$ $x$ $10^{-1}$.
