- $y^5$
- $z^{12}$
- $8a^6b^3$
- $5$
- $\frac{1}{16}$
- $\frac{9x^4}{y^2}$
- $\frac{a^5}{b^5}$
- $4$

Steps to Solve
- Question 1: Product of powers
Simplify the expression $x^3 \cdot x^5$. This tests the rule $a^m \cdot a^n = a^{m+n}$.
- Question 2: Quotient of powers
Simplify the expression $\frac{y^7}{y^2}$. This tests the rule $\frac{a^m}{a^n} = a^{m-n}$.
- Question 3: Power of a power
Simplify the expression $(z^4)^3$. This tests the rule $(a^m)^n = a^{m \cdot n}$.
- Question 4: Power of a product
Simplify the expression $(2a^2b)^3$. This tests the rule $(ab)^n = a^n b^n$.
- Question 5: Zero exponent
Simplify the expression $5x^0$. This tests the rule $a^0 = 1$.
- Question 6: Negative exponent
Simplify the expression $4^{-2}$. This tests the rule $a^{-n} = \frac{1}{a^n}$.
- Question 7: Combining product and power rules
Simplify the expression $(3x^2y^{-1})^2$. This combines power of a product and negative exponent rules.
- Question 8: Combining quotient and negative exponent rules
Simplify the expression $\frac{a^4b^{-2}}{a^{-1}b^3}$. This combines quotient and negative exponent rules.
- Question 9: Fractional exponents
Simplify the expression $16^{\frac{1}{2}}$. This tests the concept of fractional exponents representing roots.
- Question 10: Complex combination of exponent rules
Simplify the expression $\left(\frac{8x^3y^{-3}}{27x^{-6}y^6}\right)^{-\frac{1}{3}}$. This requires combining multiple exponent rules, including negative and fractional exponents.
- $x^8$
- $y^5$
- $z^{12}$
- $8a^6b^3$
- $5$
- $\frac{1}{16}$
- $\frac{9x^4}{y^2}$
- $\frac{a^5}{b^5}$
- $4$
- $\frac{3y^3}{x^3}$
More Information
Exponent rules are fundamental in algebra and are used extensively in higher-level mathematics. The ACT often tests these rules in various contexts. Mastering them is crucial for success.
Tips
- Forgetting to apply the power to all terms inside the parentheses (power of a product).
- Incorrectly adding/subtracting exponents when multiplying/dividing.
- Misunderstanding negative exponents and fractional exponents.
- Not simplifying completely (e.g., leaving negative exponents in the final answer).
- Treating the zero exponent as zero instead of one.
