Would you rather write down...,
234,000,000,000,000,000,000
or,
2.34 X 1020
Would you like to do this division in standard notation?
234,000,000,000,000,000,000/145,000,000,000
Or this?
2.34 X 1020/1.45 X 1011
Where you just divide the upper number by the lower and subtract the lower exponent from the upper exponent.
That is the advantage of scientific notation and in science you run into very large and very small numbers all the time.
how to express scientific notation to a simle number
It is: 2.9384*10^-7 in scientific notation
Scientific notation lets us express a large or a small number without having to write a lot of zeros before or after it. Try writing out 3 x 10^9000 without scientific notation.
Scientific notation is a convenient method to express very large or very small numbers.
scientific notation
because some numbers are tooo big for the screen so the calculator puts it in scientific notation form
they express the numbers using scientific notation
Sometimes. Scientific notation is used to express very small or very large numbers. If the problem does not involve any such numbers then there is no need for scientific notation.
Scientific notation provides a compact and clear way to express very large and very small numbers.
scientific notation
Write the mantissa as a negative number.
Less digits are needed for very large numbers or for very small numbers as in the following examples:- 1,000,000,000,000,000 = 1.0*1015 in scientific notation 0.000000001 = 1.0*10-9 in scientific notation
