is 225 a power of 3?
use you calculator and press
3*3=*3=*3= etc (*is a times sign)
After you press = look at the answer see if the answer is over 225. You can stop as soon as the answer is bigger than 225.
If the answer was never 225 then 225 is not a power of 3
no. it is not.
No, it isn't a power of 3: 3^4 = 81 and 3^5 = 243
But it is a multiple of 3: 3*75 = 225
