  conversion of decimal to Radix 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
  ....................................

• option-(d)
  E=14 IN HEX
  16^2*14+16^1*7+16^0*8=3704
  (3704)base7=13541
• 11 years agoHelpfull: Yes(5) No(1)
• E=14*16^2=3584
  7=7*16^1=112
  8=8*16^0=8
  sum=3584+112+8=3704
