It is 8.25*10^10.
It's best to convert those numbers from scientific notation to normal notation; that makes it easy to add them. After adding them, you can convert back to scientific notation if you want. Another option is to keep the numbers in scientific notation, but to convert them so that both have the same exponent.
20,000 + 3,400,000
It could be: 1.0*10100 in scientific notation or just 1
The exponents can be plus or minus.
The exponents can be plus or minus.
14575 + 23x101 =14805 =1.4805 x 104
Yes. Most programming languages accept scientific notation. Scientific notation is usually considered normalized if there is one digit left of the decimal point; what you write in a constant doesn't need not be normalized; but the end-result of calculations, if shown in scientific notation, will usually be normalized.
(1 + .009)¹⁰ =1.009¹⁰ =10,090,000,000
34000 + 710000 = 744000
34000 + 710000 = 744000
Scientific notation is a way to express very large or very small numbers. For very large exponent is positive; for very small exponent is negative. For example, 1,000,000 is 1 x 10 to the plus 6 exponent; 0.000001 is 1 x 10 to the negative 6 exponent
No. Scientific notation is a way of expressing very large or very small digits as factors of ten (a sort of numeric abbreviation). Ie: 2x10^8 (two times ten to the eighth power) is the same as 2x10x10x10x10x10x10x10x10, or 200000000, or conversely 2x10^-8 (two times ten to the negative 8th) is .000000002 A number in scientific notation does not change the way the math is performed. Addition, subtractio, multiplication and division will still give the same answers. In direct relation to your question, 2+2 in scientific notation would be (2x10^0) x (2x10^0) and it would equal 4 (or 4x10^0)
