To save writing out very large numbers or very small numbers that have lots and lots of noughts.
1.48, in scientific notation is 1.48 but, if you really need to show that you have written it in scientific notation, you could write it as 1.48*100
830 would not normally need be written in scientific notation. However, it would be 8.3x102
Using scientific notation reduces the need to write out very large or very small numbers as the following examples show:- 1,000,000,000,000 = 1.0*1012 in scientific notation 0.0000000001 = 1.0*10-10 in scientific notation
To write in scientific notation, you first need to divide the number by a multiple of 10 such that the answer is between 0 and 10. In this case, we get 3.9 by dividing by 100. Then you need to find what multiple of 10 your divisor is. 100 is 102. You then put these two values (3.9 and 102) together as a multiplication, and that's how you write the initial number in scientific notation: 3.9x102
To write 4100 in scientific notation, you need to move the decimal point so that there is only one non-zero digit before it. As 4100 can be written as 4.1 x 10^3.
1.48, in scientific notation is 1.48 but, if you really need to show that you have written it in scientific notation, you could write it as 1.48*100
If need be: 3.455*102

100 million in Scientific Notation = 1 x 108
You do not simply calculate scientific notation for nothing. You need a number for which you calculate the scientific notation.
To write 0000045 in scientific notation, you need to move the decimal point to the right until there is a nonzero digit to its left. In this case, it would be 4.5. Since you moved the decimal point five places to the right, the exponent will be -5. Therefore, 0000045 in scientific notation is 4.5 x 10^(-5).
To write 3,482,000,000 in scientific notation, you'll need to express it as a number between 1 and 10 multiplied by a power of 10. Here's how you can do it: 3,482,000,000 = 3.482 × 10^9 So, in scientific notation, 3,482,000,000 is 3.482 × 10^9. ʰᵗᵗᵖˢ://ʷʷʷ.ᵈⁱᵍⁱˢᵗᵒʳᵉ²⁴.ᶜᵒᵐ/ʳᵉᵈⁱʳ/³⁹⁷⁴⁶⁴/ʸᵃˢʰᵛᵃⁿᵗᵛᵃˡᵃ/
To write 4.3 in scientific notation, you would move the decimal point one place to the left, giving you 4.3 × 10^0.
To write a number in scientific notation you first need to multiply it by a power of 10 until the only digits that remain are units and decimals. In this case, we multiply by 100 to give 4.68. We multiplied by 100, and 100 is the second power of 10, or 102 so 0.0468 in full scientific notation is 4.68x102
