Question

An encryption system works by shifting the binary value for a letter one place to the left. "A" then becomes: 1 1 0 0 0 0 1 0 This binary value is then converted to hexadecimal; the hexadecimal value for "A" will be:

Answer 1

Answer:

The hexadecimal equivalent of the encrypted A is C2

Explanation:

Given

Encrypted binary digit of A = 11000010

Required

Hexadecimal equivalent of the encrypted binary digit.

We start by grouping 11000010 in 4 bits

This is as follows;

1100 0010

The we write down the hexadecimal equivalent of each groupings

1100 is equivalent to 12 in hexadecimal

So, 1100 = 12 = C

0010 is represented by 2 in hexadecimal

So, 0010 = 2

Writing this result together; this gives

1100 0010 = C2

Going through the conversion process;

A is first converted to binary digits by shifting a point to the left

A => 11000010

11000010 is then converted to hexadecimal

11000010 = C2

Conclusively, the hexadecimal equivalent of the encrypted A is C2
