Afloppy disc can store 144 bytes of data

a)write the number 144 in a standard form.

a hard disc can store 2.4x10^9 bytes of data

b)calculate the number of floppy disks needed to store the 2.4x10^9 bytes of data

We need approximately 1667 floppy disc to store bytes of data.      

Step-by-step explanation:

We are given the following information in the question:

A floppy disc can store 1440000 bytes of data.

We have to convert  1440000 in a standard form.      

Standard Form:

The standard form can be written as:

We have positive power of 10 because we have to move to the right of the decimal point.

A hard disc can store bytes of data.

Number of floppy disks needed to store the bytes of data =

Thus, we need approximately 1667 floppy disc to store bytes of data.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
