A perfect square is a number which contains a a factor that involves a number multiplied by itself. You could also say a perfect square, when taken the square root of such a number, involves a whole number answer. Either explanation would work, and there are surely mainly more haha. 25 is the perfect square because 5×5 is a factor of 25, while 50 doesn't have a factor of the same numbers.
So first simplify
(12^5)^6=(12^5)(12^5)(12^5)(12^5)(12^5)(12^5)
remember
if
(x^n)^m=x^nm
so
(12^5)^6=12^(5 times 6)=12^30
so 12^30=12^a
so a=30
Answer:

Step-by-step explanation:
this week sold = $2,760
last week sold = $2,400
the difference from this week to last week = 2700-2400 = 360
that means it increased : 360 / 2400 = 0.15 (100%) = 15%
therefore, the increase of sale is 15%
