<u>Radical As A Fractional Exponent
</u>
We can write a radical as a fractional exponent. The power to which the base is raised is the numerator and the root is the denominator. For example, the radical
is equivalent to
A) The simplification shown in the image is wrong because the student subtracted the roots of the radicals separated from the subtraction of the powers.
B) The correct procedure is
* Express both radicals as fractional exponents
* Subtract both exponents
* Simplify the resultant fraction
* Return the fractional exponent to radical form
In our case, the correct procedure is

<h3>
Answer: B) 11x^2</h3>
Explanation:
Choice A combines to 11x since the 8+3 simplifies to 11.
Choice D is a very similar story. Think of having 8 boxes, which we denote in shorthand as 8x. Then adding on 3 more boxes leads to adding on 3x. Having 8 boxes plus another 3 boxes gives 8+3 = 11 boxes total. So that's why 8x+3x = 11x. Alternatively, we can factor out the x to say 8x+3x = (8+3)x.
This shows choices A,C, and D are equivalent expressions. Choice B is the odd one out.
The equation that best represent the volume of the cylinder in cubic inches is V = π4²h.
<h3>What is a cylinder?</h3>
A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.
The volume of a cylinder is expressed as;
V = π × r² × h
Where r is radius of the circular base, h is height and π is constant pi.
Given that;
- Diameter d = 8in
- Radius r = d/2 = 8in/2 = 4in
- Height = h
- Volume of the cylinder V = ?
V = π × r² × h
V = π × (4)² × h
V = π4²h
Therefore, the equation that best represent the volume of the cylinder in cubic inches is V = π4²h.
