Someone help! Math problems

[From: ] [author: ] [Date: 12-06-02] [Hit: ]
-Observe the number in its source base (right-to-left order) and multiply each digit with the source base power by the index of that digit (starting from 0).(8 * 9^0) + (2 * 9^1) + (7 * 9^2) = 8 + 2*9 + 7*81 = 593-1434 is the base 10 for 2632 in base 8.......

Observe the number in its source base (right-to-left order) and multiply each digit with the source base power by the index of that digit (starting from 0).

Q4:
(2 * 8^0) + (3 * 8^1) + (6 * 8^2) + (2 * 8^3) = 2 + 3*8 + 6*64 + 2*512 = 1434

Q5:
(8 * 9^0) + (2 * 9^1) + (7 * 9^2) = 8 + 2*9 + 7*81 = 593

-
1434 is the base 10 for 2632 in base 8.

-
2632(base8) = 2*(8^3) + 6*(8^2) + 3*(8^1) + 2*(8^0) = 1434(base10)

728(base9) = 7*(9^2) + 2*(9^1) + 8*(9^0) = 593(base10)
