Answer:
Below in bold.
Step-by-step explanation:
c) 3 x (9^2)^3/4 x ((81^3)^5/6
= 3 x 81^3/4 x 81^15/6
= 3 x 81^(3/4 + 15/6)
= 3 x 81^13/4
= 3 x 3^13
= 3^14
= 4,782,969.
f) (5x^-1y^2)^-2 / (25 x^2 y - 1)^2
= 5^-2 x^2y^-4 / 625 x^4y^-2
= 5^-2 x^-2 y^-2 / 5^4
= 5^-6 x^-2y^-2
= 0.000064x^-2y^-2.
3y(2 - y) + 8y
6y - 3y^2 + 8y
-3y^2 + 14 y

Answer:
e. 72 inches
Step-by-step explanation:
Well, firstly to find the lengths of the sides, we would have to find the square root of 36 (which is 6, as 6x6=36).
Now, if we enlarge the square by SF 3, the new side lengths would be 6x3=18 inches. That is only one side.
Now we know the length of one side, we can do 18x4 (because as we all know, squares have 4 sides) to find the perimeter.
18x4=72 inches. This means the answer is option e.
