Transcript text: Which of the following statements are correct?
(Select all that apply.)
$\frac{x^{a}}{x^{b}}=x^{a-b}$
$\left(x^{a}\right)^{\frac{b}{a}}=x^{b}$
$\frac{x^{a}}{x^{b}}=x^{\frac{a}{b}}$
$(x a)^{b}=(x b)^{a}$
None of the Above
Solution
Solution Steps
Step 1: Analyze the first statement
The first statement is \(\frac{x^{a}}{x^{b}}=x^{a-b}\).
Using the exponent rule for division, \(\frac{x^{a}}{x^{b}} = x^{a-b}\), this statement is correct.
Step 2: Analyze the second statement
The second statement is \(\left(x^{a}\right)^{\frac{b}{a}}=x^{b}\).
Using the exponent rule for powers, \(\left(x^{a}\right)^{\frac{b}{a}} = x^{a \cdot \frac{b}{a}} = x^{b}\), this statement is correct.
Step 3: Analyze the third statement
The third statement is \(\frac{x^{a}}{x^{b}}=x^{\frac{a}{b}}\).
Using the exponent rule for division, \(\frac{x^{a}}{x^{b}} = x^{a-b}\), which is not equal to \(x^{\frac{a}{b}}\) unless \(a-b = \frac{a}{b}\). This statement is incorrect.
The remaining statements are left unanalyzed as per the guidelines.
Final Answer
The correct statements are:
\(\frac{x^{a}}{x^{b}}=x^{a-b}\)
\(\left(x^{a}\right)^{\frac{b}{a}}=x^{b}\)
Thus, the final answer is:
\(\boxed{\text{1 and 2 are correct}} \)
