expand (sqrt(x+2))^3

Solution

expand

(x + 2)^{3}

Solution

(x + 2)^{\frac{3}{2}}

Solution steps

(x + 2)^{3}

Apply radical rule:

a = a^{\frac{1}{2}}

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

Apply exponent rule:

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

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

\frac{1}{2} \cdot 3 = \frac{3}{2}

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