In a base 7 a no is written only using the digits 0 1 2-----6 The no 21 in base

21 in base 7 is written as 2*(7^1)+1=15
1234 in base 7 is written as 1*(7^3)+2*(7^2)+3*(7^1)+4*(7^0)=466
Similarly go for the other number i.e. 65432
6543 is equivalent to 2058+245+28+3=2334

Answer is: 2334+466=2800 in base 7.

Sorry for the typo earlier.

4+3=7 ie 0 in base 7 with carry 1. now 3+4+carry 1=8 ie 1 in base 7 with carry 1.similarly 2+5+1=1 and 1+6+1=1 with carry 1 giving 11110
