Scientific Notation

The mass 0.0012 grams is expressed as 1.2 X 10-3 g (1.2e-3).

6.421x103

4.803 x 106

Scientific notation is a way of writing numbers that are too big or too small to be conveniently written in decimal form.

In normalized scientific notation all numbers are written in the form a x 10^b (a times ten raised to the power of b) where a is a nonzero single-digit integer and b is an integer.

953 in scientific notation is 9.53 x 10^2

0.0067 in scientific notation is 6.7 x 10^-3

It is: 7.6*109

0.00015 is 1.5 x 10^-4

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 bis negative. For example: 23045.06 becomes 2.304506*10^4 -23045.06 becomes -2.304506*10^4 0.00023004 becomes 2.3004*10^-4 To convert a number in scientific notation to normal form: · If b is positive, move the decimal point b places to the right in the number a – adding 0s at the end of the number, if required. · If b is negative, move the decimal point b places to the left in the number a – adding 0s immediately after the decimal point, if required. · The final expression has the same sign (+ or -) as a in the scientific form. For example: 4.56*10^5 = 456000. -4.56*10^5 = -456000. 4.56*10^-5 = 0.0000456

0.006789 = 6.789 x 10^-3

It is: 7.65*10^4 which is the same as scientific notation

It is: 8.9*10^3

It is: 2.5*10^-7

It is: 9.832*10^6

It is 8.0*10^5

0000003 in Scientific Notation = 3E-06 x 106

There's nothing to change here. There is no advantage or reason to write 8.2576 in scientific notation. Technically, however, it could be written as 8.2576 × 100, but this is not normally done.

It is: 7.5*10^-12

4.35 x 10 to the eighth power

1*103 =1000

7,390,000,000 = 7.39 x 109.

19000 in scientific notation is 1.9 x 10^4.

9.234 x 10-4

1.5x10^-3

Usually number over .01 and under 1,000 are not written in scientific notation, however .85 would be written as 8.5 x 10-1.

Because this system is very convenient to deal with very small, or very large, numbers.

The answer depends on what operation you wish to perform. Since you have not bothered to provide that crucial bit of information, I cannot provide a more useful answer.
