Hence, the given number \[185,000,000\] is expressed in scientific notation as \[1.85\times {{10}^{8}}\]. Note: For writing a given number in the scientific notation, we can count the number of digits of the given number. The exponent over ten will be equal to one less than the number of digits in the given number.
Scientific notation is a format that expresses a number as a value between 1 and 10 multiplied by a power of ten. The format for scientific notation appears like this: Using scientific notation, the number 300 can be written as 3 × 10 2 which means. The 100 is written as a power of ten.
To convert any number into scientific notation, you write the non-zero digits, placing a decimal after the first non-zero digit. Then, you count the number of digits you need to move the beginning decimal to get to where your decimal is now. If you move the decimal to the left, then your power is positive.
18,900 written in scientific notation is 1.89 × 104.
Answer and Explanation:
Thus, the scientific notation of the given number is 1.8 × 10 8 .
2,100,000 written in scientific notation is 2.1 × 10 6. Simply place the decimal point to get a number between 1 and 10 and then count the digits to the right of the decimal to get the power of 10.
12 million is 1.2×107 in scientific notation.
We can represent this movement as positive 5 such that the correct scientific notation for 796,000 is 7.96 × 10 5 .
5,000,000,000 in scientific notation is 5 x 109. This is breaking the number into the digit times its place value. (Count the O's.) The 4 is in the thousandths place, so multiplying by 10-3 (1/1000) is the same as dividing by 103 (1,000).
Scientific notation is where you write a number so that it is some number between 1 and 10 that is multiplied by 10 to a power. Move over five times: 2.340000→ this number is between 1 and 10! So 2.34×105 .
7000000 = 7 × 106.
This can also be expressed as 7 × 10^6 , using the caret symbol, or as 7e+6, which is called 7000000 in e-notation, further discussed in the section ahead.
Now, the scientific notation should contain only significant figures so the digits after the decimal point are rounded off. 300,000,000 can be rewritten as $3 \times 100000000$ . Hence the scientific notation of $300,000,000$ is $3 \times {10^8}$ .
Scientific notation is essentially moving the decimal point from the end of the number to just before the first non-zero number. The number is then shown to be multiplied by an exponent of ten that accomplishes this manipulation. So, the scientific notation for 1,000,000,000 is 1 x 10 9.
25,000,000 written in scientific notation is 2.5 × 10⁷.
Put a decimal point after the first digit in 25,000,000 to get 2.5000000.
Answer and Explanation: The number 25,000 is written in scientific notation as 2.5 × 104, and the number 22,000,000 is written in scientific notation as 2.2 × 107.
\[7,000,000,000\] can be rewritten as $7 \times 1000000000$ . Hence the scientific notation of $7,000,000,000$ is $7 \times {10^9}$ .
4 . 56 × 10 , 000 , 000 , 000 = 4 . 56 × 10 10.
We can clearly see that in the given number 800,000,000 we have 8 trailing zeroes. Here, the first part of $8\times {{10}^{8}}$ is 8, which is in the range [1,10). Thus, we can say that the scientific notation of 800,000,000 is $8\times {{10}^{8}}$. Hence, the scientific notation of 800,000,000 is $8\times {{10}^{8}}$.
12,500,000 written in scientific notation is 1.25 × 107.
49,800,000 written in scientific notation is 4.98 × 107.
