Answer:
27. x^7
28. 4x^13
29. 1/f^4
30. x^5
31. 2x^14
32. (4y^3 x^2)^2
33. (2y/x)^6
Step-by-step explanation:







Coefficient of x i.e a is negative so parabola will open downwards
Graph attached
1st: 3 x 3 x 3 x 3 - we multiplied 3 5 times
2nd: 3 ^ 5 (raised to the power ^)
3rd: 3^2 x 3 ^3
(3 x 3) x (3 x 3 x 3)
9 x 27, the product is also equals to 243.
I guess it wiil be solved like this
