How do you write 0.000025 in scientific notation?

Example 2: Convert 0.000025 to scientific notation. For this, we move the decimal point 5 places to the right. 0.000025 = 2.5 x 10-5 (Note that when a number starts out less than one, the exponent is always negative.)

How do you write 0.00045 in scientific notation?

To write 0.00045 in scientific notation, write 4.5 x 10-4 The expression “4.5 x 10-4” is saying, “write 4.5 and move the decimal place four places to the left giving 0.00045.” Or you can think of it as saying 4.5 / 104 or 4.5 / 10000.

How do you write 70000000000 in scientific notation?

We are given a number that is written in standard form and we have to convert it into scientific notation. Complete step by step answer: \[7,000,000,000\] can be rewritten as $7 \times 1000000000$ . Hence the scientific notation of $7,000,000,000$ is $7 \times {10^9}$ .

How do you write 0.00000000025 in scientific notation?

(a) The starting point for quoting 0.00000000025 in scientific notation is 2.5 (the number that lies between 1.0 and 9.9). The decimal point has to be moved ten places to the left to reach 0.00000000025, so the power of ten must be –10 and the answer 2.5 × 10–10 m. (b) 2.5 × 10–4 m.

How do you write 65000000 in scientific notation?

For example, the number 65000000 would be written 6.5 x 107.

How do you write 45600000000 in scientific notation?

4 . 56 × 10 , 000 , 000 , 000 = 4 . 56 × 10 10.

How do you write 25000000 in scientific notation?

25,000,000 written in scientific notation is 2.5 × 10⁷. Count the number of digits after the decimal point. The number 2.5000000 has 7 digits after the decimal. 7 is the exponent, and we always use base 10 in scientific notation, so keep this number in mind: 10⁷

What is the scientific notation of 350000000?

Note in both examples we moved the decimal point so that there is 1 non-zero value in front of the decimal point. 350,000,000 = 3.5 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 = 3.5 x 108 This final form is the scientific notation of 350,000,000.

What is 3.8 as a scientific notation?

This time, you move the decimal point to the right, 4 spaces. N = 3.8 and x = -4. So your number in scientific notation becomes: 3.8×10-4, or 3.

What are the 3 steps to scientific notation?

1. Step 1: Move the decimal point so that you have a number that is between 1 and 10. …
2. Step 2: Count the number of decimal places moved in Step 1 . …
3. Step 3: Write as a product of the number (found in Step 1) and 10 raised to the power of the count (found in Step 2).

How do you write 30000000 in scientific notation?

To get to “standard” scientific notation, we move the decimal point so there is only one non-zero digit in front of the decimal point. So, 3,000,000 becomes 3.000,000 . The trailing zeroes are not significant, so 3.000,000 becomes 3 . We moved the decimal point six places, so the exponent is 6 .

Why do we convert numbers to scientific notation?

The primary reason for converting numbers into scientific notation is to make calculations with unusually large or small numbers less cumbersome. Because zeros are no longer used to set the decimal point, all of the digits in a number in scientific notation are significant, as shown by the following examples.
