Answer 2

Answer:

a) 3425

b) 171

c) 2603

d) 2848

Explanation:

a) 16^2*D + 16^1*6 + 16^0*1

= 256*13 + 16*6 + 1*1              (D=13 in decimal)

= 3328 + 96 + 1

= 3425

b)  16^1*A + 16^0*B

= 16*10 + 1*11            (A=10, B=11)

= 160 + 11

= 171

c) 16^2*A + 16^1*2 + 16^0*B

= 256*10 + 16*2 + 1*11

= 2560 + 32 + 11

= 2603

D) 16^2*B + 16^1*2 + 16^0*0

= 256*11 + 16*2 + 1*0

= 2816 + 32 + 0

= 2848
