<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>
Answer:
B
Step-by-step explanation:
Given the 2 equations
3x - 2y = 6 → (1)
5x + 4y = 32 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the y- term
6x - 4y = 12 → (3)
Add (2) and (3) term by term to eliminate y
11x = 44 ( divide both sides by 11 )
x = 4
Substitute x = 4 into either of the 2 equations and solve for y
Substituting into (2)
5(4) + 4y = 32
20 + 4y = 32 ( subtract 20 from both sides )
4y = 12 ( divide both sides by 4 )
y = 3
Solution is (4, 3 ) → B
Answer: no because 13(6+y) is 78+ 13y

Step-by-step explanation:
Bring the five to the other side of the equation.
Add the double negatives.
Divide. (flip the sign on account of dividing by a negative number.)
