Explanation / Answer

2.5)

e.) 10100.1101 base 2 is changed into base 10.

For that, we have

0*2^0 + 0*2^1 + 1*2^2 + 0 * 2^3 + 1*2^4 + 1*2^-1 + 1^2^-2 + 0*2^-3 + 1*2^-4

= 0 + 0 + 4 +0 +16 +0.5 + 0.25 + 0.0625

= 20.8125

h) AB3D base 16 is changed into base 10.

= 13*16^0 + 3*16^1 + 11*16^2 + 10*16^3

= 13 + 48 + 11*256 + 160*256

=43837

j.) 15C.38 base 16 is changed into base 10.

14*16^0 + 5*16 + 1*16^2 + 3*16^-1 + 8*16^-2

= 14 + 80 + 256 + 3/16 + 1/32

=94.21875
