Write 10,847,100 in Scientific Notation with 4 significant figures.

masha68 [24]

Answer:

The number 10,847,100 in Scientific Notation is $1.0847x10^{7}$

Explanation:

Scientific notation is an easy form to write long numbers and it is commonly used in the scientific field. To write a long number in a shorter way it is necessary to 'move' the decimal point to the left the number of positions that are necessary until you get a unit. Then you write the number and multiplied it by 10 raised to the number of positions you moved the decimal point. In this case, it is necessary to move the decimal point 7 positions so, we multiply the number by 10 raised to 7.
