Power of a Power
$${(a^\color{#007DDC}{m})}^{\color{#9a00c7}{n}}=a^{\color{#007DDC}{m} \times \color{#9a00c7}{n}}$$Apply the power of a power to all terms inside the bracket, then simplify.$$(-2a^{\color{#007DDC}{2}}b^{\color{#007DDC}{3}})^{\color{#9a00c7}{4}}$$ `=` $$-2^{\color{#9a00c7}{4}}a^{\color{#007DDC}{2} \times \color{#9a00c7}{4}}b^{\color{#007DDC}{3} \times \color{#9a00c7}{4}}$$ `=` `16a^8 b^(12)` `16a^8 b^(12)` -

Power of a Power
$${(a^\color{#007DDC}{m})}^{\color{#9a00c7}{n}}=a^{\color{#007DDC}{m} \times \color{#9a00c7}{n}}$$Simplify the expression by using the Power of a Power.$${\left[\frac{2x^{\color{#007DDC}{3}}}{3y^{\color{#007DDC}{2}}}\right]}^\color{#9a00c7}{3}$$ `=` $$\frac{2^{\color{#9a00c7}{3}}x^{\color{#007DDC}{3} \times \color{#9a00c7}{3}}}{3^{\color{#9a00c7}{3}}y^{\color{#007DDC}{2} \times \color{#9a00c7}{3}}}$$ `=` `(8x^9)/(27y^6)` `(8x^9)/(27y^6)` -

Nice Job!
Incorrect
Power of a Power
$${(a^\color{#007DDC}{m})}^{\color{#9a00c7}{n}}=a^{\color{#007DDC}{m} \times \color{#9a00c7}{n}}$$Quotient of Powers
$${\color{#00880A}{a}^m}\div{\color{#00880A}{a}^n}=\frac{{\color{#00880A}{a}^m}}{{\color{#00880A}{a}^n}}=\color{#00880A}{a}^{m-n}$$First, simplify the expression by using the Power of a Power.$$\frac{(3x^{\color{#007DDC}{5}})^{\color{#9a00c7}{3}}}{(x^{\color{#007DDC}{2}})^{\color{#9a00c7}{4}}}$$ `=` $$\frac{3^{\color{#9a00c7}{3}}x^{\color{#007DDC}{5} \times \color{#9a00c7}{3}}}{x^{\color{#007DDC}{2} \times \color{#9a00c7}{4}}}$$ `=` `(27x^15)/(x^8)` Simplify further using the Quotient of Powers.$$\frac{27\color{#00880A}{x}^{15}}{\color{#00880A}{x}^8}$$ `=` $$27\color{#00880A}{x}^{15-8}$$ `=` `27x^7` `27x^7` -
