A rationla power is a power in form a/b
remeber these 2 simple rules
1.

2.
![x^\frac{m}{n}=\sqrt[n]{x^m}](https://tex.z-dn.net/?f=x%5E%5Cfrac%7Bm%7D%7Bn%7D%3D%5Csqrt%5Bn%5D%7Bx%5Em%7D)
and the combo of these
![x^\frac{-m}{n}=\frac{1}{\sqrt[n]{x^m}}](https://tex.z-dn.net/?f=x%5E%5Cfrac%7B-m%7D%7Bn%7D%3D%5Cfrac%7B1%7D%7B%5Csqrt%5Bn%5D%7Bx%5Em%7D%7D)
that's all
Answer:
I think its 60x?
Step-by-step explanation:
Answer:
By unitary method
40/10 = 4km / litre
So,
4*25 = 100 km
The car covers 100km with 25 litres of fuel
Hope this helps
Please mark me as the brainliest
Thank you
30(x)<=145 and yes she would be able to make 4 bracelets because 30 x 4 = 120 and that is less than 145
Answer: The cause of exponential decay. Sowwy if im wrong
Step-by-step explanation:
An inverse variation function is not the best model because the data points show an exponential decay. The fact that this is true for ALL of the points shown indicates we have an inverse variation of the form x*y = k where k = 60 in this case. ... For any inverse variation, as x increases, y will decrease (and vice versa).
