Answer:

Step-by-step explanation:

x^2 = 27 does not produce an equivalent rational root hen we take the squre root of vboth sides: x = plus or minus sqrt(27). sqrt(27) IS irrational. So is ghe equivalent x = ±√(3^3) = ±3^√3

x^2 = 1 simplifies to ±1, which is rational.

A music store buys compact discs for $12 each and sells them for $15 each. What is the percent of markup?

If we take 12 to be the 100%, now 15 - 12, so is 3 bucks up for the retail price, what is 3 off 12 in percentage then?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
12&100\\
3&p
\end{array}\implies \cfrac{12}{3}=\cfrac{100}{p}\implies p=\cfrac{3\cdot 100}{12}$
