Answer 1

2)
converting binary numbers to decimal:
a)
1010 = 1*2^3 +0*2^2 +1*2^1 +0*2^0 = 8+2 = 10 in decimal
b)
110110 = 1*2^5 +1*2^4 +0*2^3 +1*2^2 +1*2^1 +0*2^0 = 32+16+4+2 = 54
c)
01110000 = 0*2^7 +1*2^6 +1*2^5 +1*2^4 +0*2^3 +0*2^2 +0*2^1 +0*2^0 = 64+32+16 =112
d)
10011111 = 1*2^7 +0*2^6 +0*2^5 +1*2^4 +1*2^3 +1*2^2 +1*2^1 +1*2^0 = 128+16+8+4+2+1=159
