To compare numbers in scientific notation, first check the exponent. Whatever exponent is higher is the greater number. If the exponents are the same, check the first number. Whatever first number is higher is the greater number.
5.7 x 10^3 is greater than 3.89 x 10^3
2.66 x 10^5 is greater than 8.57 x 10^2

To compare numbers in scientific notation, compare the coefficients (the numbers before the multiplication symbol) first. The larger coefficient indicates the larger number. If the coefficients are the same, then compare the exponents. A greater exponent implies a larger number, while a smaller exponent indicates a smaller number.

Why are the very large and very small numbers usually written in powers of ten?
That gives a better overview. It's easier to compare two large numbers (or small numbers) written in scientific notation than if they are written out. When the numbers are written out, you have to count digits, which can be slow, error-prone, and basically useless. When the number is in scientific notation, the counting has basically already been done for you. To compare two numbers in normalized scientific notation, just compare the exponents.
What is the purpose about scientific notation?
The idea is to show very large numbers, or very small numbers (close to zero) in a concise notation. If you write down the mass of the Sun in kilograms, it is very cumbersome; also, you have to count the digits to compare with some other number (such as the mass of another star); with scientific notation, you can immediately compare two such numbers.
Is scientific numbers and scientific notation the same?
No. Scientific numbers are constants that appear in science. They may or may not require scientific notation.
What is the disadvantage of using scientific notation?
If you are adding or subtracting two numbers in scientific notation, you must rewrite one of the numbers to the same power of ten as the other, before performing the addition (or subtraction).
What are 2 ways of writing numbers?
standard notation and scientific notation For example: 126,000 is standard notation. 1.26X105 is scientific notation.

How does writing numbers in scientific notation make it easier to compare and order the numbers?
I think because it has little numdres

how to express scientific notation to a simle number
What is the express numbers in 0.00000029384 in scientific notation?
It is: 2.9384*10^-7 in scientific notation
What requires scientific notation?
Scientific notation is required for very large or very small numbers.
How does scientific notation differ from ordinary notations?
Ordinary notation is where the numbers are laid, or written out. Scientific notation is a short handed version with numbers that indicate the amount of zeroes behind the end of the numbers.
Scientific notation for metric units?
Scientific notation is scientific notation - whether it is used for metric units, Imperial units or simply for numbers.
Why is scientific notation useful in economics?
Scientific notation is useful in economics to compute very large or very small numbers.
