<span><u><em>The correct answer is: </em></u>
we cannot take an even root of a negative number in the real number system.
<u><em>Explanation</em></u><span><u><em>: </em></u>
A rational exponent is another way of writing a root. The denominator of the rational exponent will be the root, and the numerator will be the power of the number under the root. If the denominator is even, this means we are taking an even root, such as square root, 4th root, etc.
If the base is negative, this means we want an even root of a negative number.
Any even root can be broken down into a series of square roots, done one after another.
However, we cannot take the square root of a negative number using real numbers; this is because a square root is a number multiplied by itself to get the answer; a negative times a negative is a positive, as is a positive times a positive, so there is no way to multiply the same number twice and get a negative.</span></span>

The size of the brand name will be 12 inches by 23 inches.
The complete question is given below:-
Jesse considered two similar televisions at a local electronics store. The generic version was based on the brand name and was two-thirds the size of the brand name. If the generic television set is 18 inches by 34 inches, what are the dimensions of the brand-name television? Round to the nearest inch.
12 inches by 23 inches
23 inches by 38 inches
25 inches by 40 inches
27 inches by 51 inches
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Given that:-
- Jesse considered two similar televisions at a local electronics store. The generic version was based on the brand name and was two-thirds
- The size of the brand name. If the generic television set is 18 inches by 34 inches,
The size of the brand name will be calculated as:-
Size = 
Size = 
Therefore the size of the brand name will be 12 inches by 23 inches.
