Answer:
−y−1=3
Step-by-step explanation:
Which equation can be used to find the solution of (1/4)^y+1=64?
This can be solved by power of indices
(1/4)^(y+1)=64
(4^-1)^(y + 1)= 4^3
Note
(x^a)^b = x^ab
Hence:
4^(-1)(y + 1)= 4^3
4^-y - 1 = 4^3
Divide both sides by 4
−y−1=3
Hence, the equation that can be used to find the solution of (1/4)^y+1=64 is
−y−1=3

Answer:
76 square feet
Step-by-step explanation:
2 x 4 = 8 x 2 = 16
5 x 4 = 20 x 2 = 40
2 x 5 = 10 x 2 = 20
16 + 40 + 20 = 76
