Answer: Hii my name is Alice and here is the answer for your question: 2.917 × 10 exponent 6

Explanation:

  1. Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.
  2. Count how many places you moved the decimal point. This number is b.
  3. If you moved the decimal to the left b is positive.
  4. If you moved the decimal to the right b is negative.
  5. If you did not need to move the decimal b = 0.
  6. Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b."
  7. Remove trailing 0's only if they were originally to the left of the decimal point.

Answer:
2.917
x
10^(6)

Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.

So here, we have 2.917000 and notice that there

is only one digit to the left of the decimal point.

Next, we count the number of places the decimal point would

need to move to get back to the original number, 2,917,000.

Since we would need to move the decimal point 6 places to the right, we have an exponent of positive 6.

Now, scientific notation is always expressed as a number between 1 and 10 including 1 but not 10 and it is multiplied by 10 to a certain power that must be an integer.

So we have
2.917000
x
10^(6).

Notice that the exponent is positive.

This is because we would need to move the decimal point to the right in order to get back to the original number.

So 2,917,000 can be written in scientific notation

as
2.917000
x
10^(6) or just
2.917

Remember that we can drop zeroes at the end of a decimal.

So we have
2.917
x
10^(6).
