Answer 1

Answer:

the two digit number ab when reversed can be expressed as ba

Answer 2

Answer:

10b +a or simply ba

Step-by-step explanation:

The two digit number ab is written as:

10a +b×1

[ Eg: 26 = 2×10 + 6×1]

If we reverse the digits we get the number ba which can be written as 10b + a×1

Why do we multiply the first digit in a 2-git number by 10 and the second digit by 1?

It is because we follow a base 10 system in Maths while writing number.
