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:
Step 5 is incorrect because a previous step is incorrect
Step-by-step explanation:
Step 1 correct
Step 2 correct
Step 3 correct
Step 4 incorrect: It must be
y² - 10y + 25 = 2x + 23
Step 5 incorrect because step 4 incorrect
Step 5 must be : 1/2(y - 5)² - 23/2 = x
Answer:idk
Step-by-step explanation:
The first thing to notice with this question is that the volume of the tank is given in cm3 yet the rate at which the water leaks is in litres, so a conversion of units will be neccessary. We know that there are 1000cm3 for every litre so 45000cm3 is equivilent to 45 litres (45,000/1000 = 45). So what do we know now? Well the tank of water contains 45 litres, and every minute 0.75 litres is lost, so our objective is to find out how many miuntes go by before the tank is empty. In other words how many 0.75s go into 45, luckily division can help us out. 45/0.75 = 60 minutes.
Mark brainliest please
Hope this helps you
