First of all, you should know/notice that
![125=5^3](https://tex.z-dn.net/?f=125%3D5%5E3)
You should also know how negative exponents work:
![a^{-m}=\dfrac{1}{a^m}](https://tex.z-dn.net/?f=a%5E%7B-m%7D%3D%5Cdfrac%7B1%7D%7Ba%5Em%7D)
So, if you wanted
![5^x=125](https://tex.z-dn.net/?f=5%5Ex%3D125)
the answer would be x=3, but since you want 125 to be at the denominator, the answer is x=-3:
![5^{-3}=\dfrac{1}{5^3}=\dfrac{1}{125}](https://tex.z-dn.net/?f=5%5E%7B-3%7D%3D%5Cdfrac%7B1%7D%7B5%5E3%7D%3D%5Cdfrac%7B1%7D%7B125%7D)
Answer:
10p-40 = 10(p-4) this is the answer of this question
Answer:
37.5 ( i didn't round cause the answer looked simple already)
Step-by-step explanation:
formula for triangle is base x height divided by 1/2
Base(5) x Height(15) = 75 now divide by 1/2
75 divided by 1/2 = 37.5

Answer:
Step-by-step explanation:
The first term must have one number before decimal point
the second term (factor) must be 10 having some power.
