Correct option is C. He has 225 acres of land .
Let the Number of acres of land Roy have = x
As he planted corn on  1/5  of his land,
Number of acres of his land planted with corn =  1/5  × Number of acres of land Roy have
 =  x/5 
As he planted 45 acres of his land with corn,
⇒ x/5
  = 45
⇒x = 45 × 5
⇒x = 225
Therefore, number of acres of land Roy have is   225  .

Answer:Thus,  (-3)-4 = 1/(-3)4.
Step-by-step explanation:
Negative exponents have the following property:   n-m = 1/nm   OR   1/n-m = nm
So for  (-3)-4 ,  n= -3 and -m= -4 (or m= 4).
Thus,  (-3)-4 = 1/(-3)4.
