simplify \sqrt[3]{27^{x+5}}

Solution

simplify

Solution

3^{x + 5}

Solution steps

Apply radical rule:

= (2 7^{x + 5})^{\frac{1}{3}}

Apply exponent rule:

(a^{b})^{c} = a^{b c}

= 2 7^{(x + 5) \frac{1}{3}}

Simplify

(x + 5) \frac{1}{3} : \frac{x + 5}{3}

= 2 7^{\frac{x + 5}{3}}

Factor the number:

27 = 3^{3}

= (3^{3})^{\frac{x + 5}{3}}

Apply exponent rule:

(a^{b})^{c} = a^{b c}

(3^{3})^{\frac{x + 5}{3}} = 3^{3 \cdot \frac{x + 5}{3}} = 3^{x + 5}

= 3^{x + 5}
