How much is a billion in scientific notation?
1 billion can be written as 1,000,000,000 or represented as 109 . How would 2 billion be represented? Since 2 billion is 2 times 1 billion, then 2 billion can be written as 2×109 2 × 10 9 .
How do you write 1,000,000,000 in scientific notation?
Scientific notation is essentially moving the decimal point from the end of the number to just before the first non-zero number. The number is then shown to be multiplied by an exponent of ten that accomplishes this manipulation. So, the scientific notation for 1,000,000,000 is 1 x 10 9.
How do you convert to scientific notation?
To convert a number to scientific notation, place or move the decimal point of a number until the coefficient of the number is greater than 1 and less than 10. Record down the coefficient (a) and count the number of steps the decimal point was moved. The number of steps moved (n) is taken as the exponent.
How do you solve scientific notation problems?
To convert to scientific notation, start by moving the decimal place in the number until you have a coefficient between 1 and 10; here it is 3.45. The number of places to the left that you had to move the decimal point is the exponent. Here, we had to move the decimal 4 places to the right, so the exponent is -4.
How do you write $1 billion?
1,000,000,000 (one billion, short scale; one thousand million or milliard, yard, long scale) is the natural number following 999,999,999 and preceding 1,000,000,001. One billion can also be written as b or bn. In standard form, it is written as 1 × 109.
How do you write out 2.2 billion?
We start by showing you how to write 2.2 billion, or two point two billion, in words. two billion two hundred million.
What is millionth in scientific notation?
0.000 001
One millionth is equal to 0.000 001, or 1 x 10−6 in scientific notation. It is the reciprocal of a million, and can be also written as 1/1 000 000. Units using this fraction can be indicated using the prefix “micro-” from Greek, meaning “small”.
How do you write 0.00006 in scientific notation?
We can find the scientific form of \[0.00006\] by simply writing the digit 6 to the left of decimal and multiplying with \[{{10}^{-5}}\].
How do you write 420000 in scientific notation?
420,000 (four hundred twenty thousand) is an even six-digits composite number following 419999 and preceding 420001. In scientific notation, it is written as 4.2 × 105.
How do you write 0.00001 in scientific notation?
We know that when we move the decimal to the right then $ b $ is negative. Thus, $ b = – 5 $ . Hence, the scientific notation of \[0.00001\] is $ 1 \times {10^{ – 5}} $ .
How is one billion written in scientific notation?
Billion. One billion in scientific notation is 1, and we place 10 to the power of 9. Means 1 billion is 1×10 9. Here we need to figure out the number we are raising 10. Then observe when to move the decimal point; we move 9 places to the left. If you move the decimal to the left, you will raise 10 to the power of n.
How are small numbers converted to scientific notation?
Very small numbers are converted to an equivalent decimal number between 1 and 10, multiplied by 10 raised to some negative power. In this example scientific notation calculation we’re solving 1.225 × 10 5 + 3.655 × 10 3 : E notation is also known as exponential notation.
Which is the power of 10 for scientific notation?
b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number. Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a. Count how many places you moved the decimal point.
How big is the problem of poverty in the world?
Poverty is still a big problem in the world today, as you can see from the numbers. This is in spite of the progress that you see around you. The good news is that in 2010, only 18% of the world’s population was living way below the poverty line as compared to 36% in 1990. It’s a small victory, but the progress is slow.
