8.8 × 10-3 written in decimal notation is 0.0088
-3/8 = -0.375
93.375 is 93 3/8. On a calculator, divide 3 by 8 to find the decimal.
Take the diameter, then divide by 2 to get the radius. To get to scientific notation, put the number in the form of one digit followed by a decimal point, then the rest of the number, followed by x10n, where n is the number of places that you had to move the decimal point to get just one digit to the left of the decimal point. For example: diameter of 8. Divide by 2 to get 4. To get to scientific notation, make it 4X100. You didn't have to move the decimal point at all, so n=0. Example #2: Diameter of 250. Divide by 2 to get radius, which is 125. To make it scientific notation, you have to move the decimal point 2 places to get 1.25X102. If you had to move the decimal point to the right, then make n a negative number. Example #3: Diameter of 1/10. Divide by 2 to get radius of 1/20, or 0.05, which in scientific notation is 5X10-2.
decimal notation for 4 3/10 = 4.30
The standard decimal notation is 8,754.4The scientific notation is: 8.7574 x 10^3
2.4 X 10-3 I moved the decimal 3 places. Each time you move the decimal one place, you increase the power of 10 by 3. Since the decimal has to be moved back to the left 3 spots, the 3 is a negative.
2400 = 2.4 x 10^3 0.0024 = 2.4 x 10^-3 Move the decimal to the left, positive exponent. Move the decimal to the right, negative exponent.
The decimal notation of 2552 over 125 is 20.416 to the accuracy of 3 decimal places.
The decimal would be negative. Ex: -2/3 is -0.67
If the exponent is positive, you move the decimal point to the right, the specified number of digits. For a negative exponent, you move it to the left. In either case, you fill out missing digits with zero. Examples (using "^" for power):3.448 x 10^1 = 34.485 x 10^6 = 5000000 (note the implied decimal point to the right of the number)3 x 10^-3 = 0.003
You were trying to write in scientific notation? 0.000032 * 10^-3 = 0.000000032 If the exponent is negative, move the decimal place to the left. If it's positive, move the decimal place to the right.
