5^9/5^5= 625
You can either change the exponents to their equivalent whole numbers or subtract exponents.
The answer could also be represented as 5^4
x÷(-4)-5 > -2

Answer:
1/5 or 20%
Step-by-step explanation:
The total number of paintings is 60.
60 = x (x − 2) + x + 2x + 8 + 10
60 = x² − 2x + x + 2x + 18
0 = x² + x − 42
0 = (x + 7) (x − 6)
x = -7 or 6
Since x can't be negative, x = 6. So the number of paintings from the 20th century is 6 (6 − 2) + 6 = 30.
The number of paintings that are both British and from the 20th century is 6.
So the probability that a painting from the 20th century is also British is 6/30 = 1/5, or 20%.
Each cut will double the number of slices, so if the recurrence starts with
![n=1](https://tex.z-dn.net/?f=n%3D1)
, then you have
![p(n)=2^{n-1}](https://tex.z-dn.net/?f=p%28n%29%3D2%5E%7Bn-1%7D)
.
![p(1)=2^{1-1}=2^0=1](https://tex.z-dn.net/?f=p%281%29%3D2%5E%7B1-1%7D%3D2%5E0%3D1)
corresponds to the whole pizza (one "slice").
The first cut gives
![p(2)=2^{2-1}=2^1=2](https://tex.z-dn.net/?f=p%282%29%3D2%5E%7B2-1%7D%3D2%5E1%3D2)
slices, and so on.
