By the power rule, the radical expression become
. Hence expressing
as a radical is ![\sqrt{7}](https://tex.z-dn.net/?f=%5Csqrt%7B7%7D)
<h3>Power rule in indices </h3>
Given the expression;
![(\sqrt{7} )^2](https://tex.z-dn.net/?f=%28%5Csqrt%7B7%7D%20%29%5E2)
This is expressed as;
![(\sqrt{7})^2 = (7^{\frac{1}{2} })^2\\(\sqrt{7})^2 = 7^{\frac{1}{2} \times 2}\\(\sqrt{7})^2=7^1\\(\sqrt{7})^2 =7](https://tex.z-dn.net/?f=%28%5Csqrt%7B7%7D%29%5E2%20%3D%20%287%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%7D%29%5E2%5C%5C%28%5Csqrt%7B7%7D%29%5E2%20%3D%207%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%202%7D%5C%5C%28%5Csqrt%7B7%7D%29%5E2%3D7%5E1%5C%5C%28%5Csqrt%7B7%7D%29%5E2%20%3D7)

Adding odd numbers will only give you an even sum if the amount of numbers you added is an even number.
For example,
25 is an odd number. If you add 25, 2 times (2 is an even number) you will get 50 (an even number). If you add 25, 4 times (4 is an even number) you will get 100 (still, an even number)
However, if you add 25, 3 times (an odd number) you will get 75 (an odd number). If you add 25, 5 times (an odd number) you will get 125 (still an odd number).
Hopefully, that helped (: Sorry if I confused you lol
The answer is b -an increase in income will cause the demand curve of an inferior good to shift to the left.
Explanation: An inferior good is a good whose demand reduces as income increases. It's demand has an inverse or negative relationship with income. Therefore as the income of the individual increases, the demand for an inferior good reduces. On a graph, the reduction in demand is depicted by an inward shift of the demand curve or a shift of the demand curve to the left to show a reduction in demand. Income is one of the factors that leads to a shift in the demand curve. The income elasticity would be negative
