1 Expressing Numbers in Science Chapter 1 Scientific Notation Scientific Notation has you express numbers in terms of exponentials . An exponential is a number multiplied by itself a certain number of times. 4 3 = 4 x 4 x 4 = 64 10 6 = 10 x 10 x 10 x 10 x 10 x 10 = 1,000,000 Scientific notation uses only exponentials of 10. In scientific notation, values are expressed as a number in decimal form where 1 n < 10 multiplied by 10 raised to a power. Scientific Notation To change a number 10 to scientific notation, count how many times you are moving the decimal to the left to change the number to a number between 1 and 10. That number is the number of factors of 10 you are dividing out of the number and will be the exponent on the 10 in scientific notation. 9 8 7, 0 0 0 = 9.87 x 10 5 Scientific Notation To change a number < 1 to scientific notation, count how many times you are moving the decimal to the right to change the number to a number between 1 and 10. That number is the number of factors of 10 you are multiplying into the number and the negative of that number will be the exponent on the 10 in
