70,120 Converted to Scientific Notation

Scientific Notation: m x 10ⁿ, 1 ≤ m < 10 and n is an integer
Conversion Procedure for a Given Number in Standard Form:

• Move the decimal point to where there is only one digit greater than 0 to its left
• Moving the decimal point n places to the left corresponds to a positive n (n), and moving the decimal point n places to the right corresponds to a negative n (-n)
• m is equal to the number formed by the digit to the left of the new decimal point location, and any digit(s) to its right less trailing 0s

Application of Conversion Procedure to 70,120 (70,120.0)

• There are 5 digits to the left of the decimal point
• Therefore the decimal point needs to be moved 4 places to the left (n = 4)
• After the decimal point is moved, the digit to its left is 7, and less the trailing 0, the digits to its right are 012
• As a result, m = 7.012
• In Scientific Notation: 70,120 = 7.012 x 10⁴
