Q1:

a)                  Convert (1000100)2 into decimal equivalent.

Binary = 1000100

Decimal= 1×2⁶+0×2⁵+0×2⁴+0×2³+1×2²+0×2¹+0×2⁰

= 68

Signed decimal = (68)10

how to type 2 raise to power 6 ?

use ctrl+shift and (+) to write exponent

)                  Convert (1000100)2 into decimal equivalent.

(1000100)2 =   (1 * 26  + (0*25) + (0*24) + (0*23) + (1*22) + (0*21) + (0*20)

= 64 + 0 + 0 + 0 + 4 + 0 + 0

= 64+4

= (68)10

 

b)                 Convert (68)10 into binary equivalent.

 

        2       68                                               Remainders

                              34                                                       0

                              17                                                       0

                              8                                                         1

                              4                                                         0

                              2                                                         0    

                              1                                                         0

 

                   Hence, (68)10 = (1000100)2
