How do you write 0.0078125 in scientific notation
To write 0.0078125 in scientific notation, we move the decimal point to the right until only one non-zero digit remains in front of it. We count the number of places we moved the decimal point, and this becomes the exponent.
So, 0.0078125 in scientific notation is 7.8125 x 10^(-3).
What is the number 5.9 * 10 to the 5th power written in decimal notation
The number 5.9 x 10^5 in decimal notation is 590,000.
suppose an average person blinks 15 times per hour how many times does an average person blink in a year write the answer in scientific notation hint one year equals 365 days one day equals 24 hours
If an average person blinks 15 times per hour, then the person blinks 15 x 24 = 360 times in a day (assuming 24 hours per day).
In a year, with 365 days, the person blinks 360 x 365 = 131,400 times.
To write this in scientific notation, we can express it as 1.314 x 10^5 times.
To write 0.0078125 in scientific notation, follow these steps:
Step 1: Determine the first non-zero digit. For this number, it is 7.
Step 2: Move the decimal point so that only one digit remains to the left of it. In this case, move the decimal point four places to the right, since there are four digits (including zeros) that need to be moved.
0.0078125 becomes 7.8125.
Step 3: Write this number as a decimal between 1 and 10. In this case, it is 7.8125.
Step 4: Add the appropriate power of 10 to the scientific notation. The power is the number of places the decimal point was moved in Step 2. Since we moved four places to the right, the power is -4.
Therefore, 0.0078125 in scientific notation is 7.8125 × 10^-4.
To write a number in scientific notation, you need to express it as the product of a decimal number between 1 and 10, and a power of 10. Here's how you can write 0.0078125 in scientific notation:
Step 1: Identify the non-zero digit
The non-zero digit in 0.0078125 is 7.
Step 2: Determine the decimal exponent
Count the number of places the decimal point needs to be moved to the right so that the non-zero digit is to the left of the decimal point. In this case, the decimal point needs to be moved 4 places to the right to have 7 on the left side of the decimal, resulting in 0.00000078125.
Step 3: Express the number in scientific notation
Now, express the number in scientific notation by multiplying the non-zero digit by 10 raised to the power of the decimal exponent. Therefore, 0.0078125 in scientific notation is written as 7.8125 × 10^-4.
To summarize, 0.0078125 in scientific notation is 7.8125 × 10^-4.
