- @Aanantha Yazhisai,
Pls check .
E78-(8*16^0)+(8*16^2)+(8*16^3)= 3704 is not correct.
It should be
E78 in hexadecimal = (8*16^0)+(7*16^1)+(14*16^2)= 3704 base 10
3704 base 10 = 13541 base 7 - 11 years agoHelpfull: Yes(23) No(0)
- First Convert Hexadecimal into decimal then into base 7.
Hexa todecimal
......................
E78-(8*16^0)+(8*16^2)+(8*16^3)= 3704
Decimal to Base 7
................................
3704/7:reminder:1 and dividend:529
529/7:reminder:4 and dividend:75
75/7:reminder:5 and dividend:10
10/7:reminder:3 and dividend:1
1/7:reminder 1
....................................
Then finally result is:13541 - 11 years agoHelpfull: Yes(21) No(8)
- friends firstly we convert E78 to decimal
14*16^2+7*16^1+8*16^0=3704.
now 3704/7=529 and the reminder is 1
now 529/7=75 and the reminder is 4
now 75/7= 10 and reminder is 5
then 10/7=1 and reminder is 3
now 1/7 reminder is 1
now count from lsb 13541 will be a correct ans..... - 11 years agoHelpfull: Yes(11) No(0)
