Scientific notation is a way of representing numbers, usually very large or very small, in the form a*10^b where 1 ≤ |a| < 10 is a decimal number and b is an integer (negative or positive). a is called the mantissa and b is called the exponent. To convert a number to scientific notation: · If the number has no decimal point, then add one at the end. · Then move the decimal point to just after the first digit while counting the number of places you have moved it. · The mantissa of the new number, formed after moving the decimal point is a. · If the original number is negative, then so is a. · The number of places to the left that the decimal point was moved is b. If it was moved to the right, then b is negative.
Sorry, but the above procedure takes five operations.

Note that the term is the same as 34000.0. Then, move 4 decimal places to the left and write out: 3.4 x 104.
in standard form? 2.4*10^5 stick the decimal point between the 2 and the four: the first two digits, then how many places would you have to move the decimal to get back to the original number? this is equal the a multiple of ten each time, so we say, in this case, you would have to move the decimal 5 places to the right, so its *10^5 where ^ indicates that its a raised to the power sign, and * indicates we multiply. For example x squared is x^2 in this notation, and the only reason I'm having to use it, is because there is no way for my keyboard to write common maths easily. Using ^ and * in this answer is not part of the standard form notation, and you would just write it out normally: 2.4 times 10 to the power of 5. This notation is called standard index form.
2.48e-6 or 2.48 x 10^-6
9 x 10^4 (nine times ten to the four) The method of using scientific notation is never having the main number be greater than 10 and using 10 exponent a number to make up for the missing place value- 2747663 would be 2.747663 x 10^6 (because the decimal moves 6 places) :) Katie
8,436 in Scientific Notation = 8.436 x 103
It is: 400,000,000,000,000 or as 1.0*10^14 in scientific notation
It is: four hundred and eighty million or as 4.8*108 in scientific notation
4.68*10 to the third power
Scientific notation is 4.4 * 106 > four million, four hundred thousand > 4.4 million
1.2 x 10^(-4) What this says is that you write 1.2 and move the decimal to the left four places.
400,000,000 in Scientific Notation = 4 x 108
Four billion in Scientific Notation = 4 x 109
33,400,000,000,000,000,000,000 in words is: thirty-three sextillion four hundred quintillion.
Shift four decimal places to the right from the starting position to get: 4.15 x 10-4
To write 49000 in scientific notation, move the decimal point to the left so that there is only one non-zero digit to the left of the decimal point. In this case, it would be 4.9. Then, count the number of places the decimal point was moved. In this case, it was moved four places to the left. Therefore, 49000 in scientific notation is 4.9 x 10^4.
The best option for such large numbers is to write (and pronounce) them in scientific notation.
