Answer:

Step-by-step explanation:

32²=(40-8)²

=40²-2(40)(8)+8²

=1600-640+64

=1664-640

=1024

also 32²=1024

The two digit number should be 32.

  • The calculation is as follows:

[tex]32^2=(40-8)^2\\\\=40^2-2(40)(8)+8^2[/tex]

Now

=1600-640+64

=1664-640

=1024

Moreover, the square of 32  is 1024
