Name: ____________________________________________ Scientific Notation Date: __________________ How to find scientific notation: 1. Find your first NON-ZERO number, reading from left to right. Ex: 0.00042 (4 is your first non-zero number) 2. Move the decimal place so that it is right after the first non-zero number. Ex: 0.0004.2 3. Count how many places you moved the decimal point. Ex: if you had to move 4 places 0.0004.2 4. Determine if your exponent should be positive or negative. If you moved the decimal to the right your exponent is negative, but if it moved to the left the exponent is positive. 5. Your answer should be written with your constant multiplied by ten to a positive or negative power. Ex: 4.2 × 10−4 Write the following numbers in scientific notation: 1) 0.00052 5.2 x 10-4 7) 6,077,900 6.0779 x 106 2) 2,897,000 2.897 x 106 8) 0.0012890 1.2890 x 10-3 3) 0.1234000 1.234 x 10-1 9) 5,000,000 5 x 106 4) 8,000,000,000 8 x 109 10) 0.0045098 4.5098 x 10-3 5) 4,876,000 4.876 x 106 11) 4,235,000,000 4.235 x 109 6) 0.00000678 6.78 x 10-6 12) 1,879,300,000,000 1.8793 x 1012 Doing the Math with Scientific Notation: 1. If you are multiplying you must multiply your factors and add your exponents. 2. If you are dividing you must divide your factors and subtract your exponents.
