Answer 1

Answer:

The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

• 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.
• Count how many places you moved the decimal point. This number is b.
• If you moved the decimal to the left b is positive.
• If you moved the decimal to the right b is negative.
• If you did not need to move the decimal b = 0.
• Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b."
• Remove trailing 0's only if they were originally to the left of the decimal point.
