Write the following number in scientific notation.
1,291,000
1.291 × 10^6
To write the number 1,291,000 in scientific notation, follow these steps:
1. Move the decimal point to the right of the first non-zero digit, which gives us 1.291000.
2. Count the number of places the decimal point moved to the right. In this case, it moved 6 places to the right.
3. Rewrite the number as the product of a number between 1 and 10 (the decimal part) and 10 raised to the power of the number of places the decimal moved.
Therefore, 1,291,000 in scientific notation is written as 1.291 × 10^6.
To write a number in scientific notation, you need to express it as a product of a number between 1 and 10, and a power of 10.
To write the number 1,291,000 in scientific notation:
1. Start by moving the decimal point to the left until there is only one non-zero digit to the left of the decimal point. In this case, moving the decimal point three places to the left gives us 1.291000.
2. Next, count the number of decimal places you moved the decimal point. In this case, we moved it three places to the left, so the exponent of 10 will be positive 3.
3. Finally, write the number in the format a x 10^b, where 'a' is the number you obtained in step 1, and 'b' is the exponent of 10 from step 2.
Therefore, 1,291,000 written in scientific notation is 1.291 x 10^6.
