Question

Write 2.71x10-3 as an ordinary number.​

Answer 1

Explanation:

`{2.71 * 10}^( - 3)`

This can be rewritten as

`2.71 * (1)/(10^(3) )`

If we will solve this way,

`(2.71)/(1000) = 0.00271`

But since the denominator is just in terms of 1, we can just simply get the (-3). Note that we have to take the negative into consideration.

From the original position of the decimal point, move the decimal point 3 times TO THE LEFT. Therefore, from 2.71 we move the decimal point 3 times to the left, 0.00271.

If the exponent has a positive value, move TO THE RIGHT.

For example,

`2.71 * {10}^(3) = 2.71 * 1000 \\ = 2710`

Note that the exponent has a positive value. Therefore, we have to move the decimal point 3 times TO THE RIGHT. Producing 2710 as the answer.
