You love football and want to start practicing your throw daily . The first day you practice for 3 minutes. The next day you triple your time . You continue to triple your practice time everyday. How many minutes did you practice on the 4th day ?
3^4 power is the same as tripling your time 4 times, so 3x3=9 (day 2) 9x3=27 (day 3) and 27x3= 81 (day 4) so you practice for 81 minutes on the 4th day
