because those are the correct ones :)
the first option is the answer
Step-by-step explanation:
4c + 6a <= 120 [building hours]
4c + 4a <= 100 [testing hours]
4 * 20 + 6 * 6 <= 120
80 + 36 <= 120
116 <= 120
true, they have enough building hours
4 * 20 + 4 * 6 <= 100
80 + 24 <= 100
104 <= 100
false, they won't have enough testing hours
the first option is the answer
Well, 625 is 5 x 5 x 5 x 5 .
So that would be:
(5)⁴
5 x (5)³
(5)² x (5)²
And you could even go the other way if you want to get silly:
(5)⁵ x (5)⁻¹
(5)⁶ x (5)⁻²
.
.
etc.
