    How many hours would it take to type 3.2 x 10^5 words?

    Standard form is used in expressing large numbers in smaller numbers. It is used to transform large numbers into smaller number.
    In order to write a number in standard form, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
    For example: 1 x 10² is equivalent to 100
    The first step is to determine how many words he can type in 1 hour : 40 x 60 = 2400 words = 2.4 x 10³
    The second step is to divide 3.2 x 10^5 words by 2.4 x 10³
    3.2 x 10^5 ÷ 2.4 x 10³ = 1.33 x 10^(5 – 3)
    1.33 x 10^2  hours
