In Exercises 77–86, write each number in scientific notation. −3829
Verified step by step guidance
1
Identify the significant digits in the number, which are 3829.
Determine the position of the decimal point in the original number. Since it's a whole number, the decimal is after the last digit: 3829.
Move the decimal point to the left until only one non-zero digit remains to the left of the decimal. For 3829, move the decimal 3 places to the left to get 3.829.
Count the number of places the decimal point was moved. In this case, it was moved 3 places.
Express the number in scientific notation as , where the exponent is positive because the original number is greater than 1.

Scientific Notation
Scientific notation is a way of expressing numbers that are too large or too small in a compact form. It is written as the product of a number between 1 and 10 and a power of ten. For example, the number 3829 can be expressed as 3.829 × 10^3 in scientific notation.
When writing negative numbers in scientific notation, the process is similar to positive numbers, but the coefficient remains negative. For instance, the number -3829 would be expressed as -3.829 × 10^3, indicating that it is a negative value while still adhering to the scientific notation format.
Converting a number to scientific notation involves identifying the significant figures and determining the appropriate power of ten. This requires moving the decimal point in the number until only one non-zero digit remains to its left, which helps in simplifying calculations and comparisons in scientific contexts.
