Calculate 243six s i x – 243five f i v e expressing your answer in base 10.

Calculate 243${}_{six}$ – 243${}_{five}$ expressing your answer in base 10.

Answer Details

Since they are of different base, convert to base 10
243${}_{six}$ = (2 x 62) + (4 x 61) + (3 x 60)
= 72 + 24 + 3 = 99 base 10
243${}_{six}$ = 2 x 52 + 4 x 51 +3 x 50
50 + 20 + 3 = 73 base 10
Subtracting them, 99 - 73
= 26
