expand (3+h)^3

Solution

expand

(3 + h)^{3}

Solution

27 + 27 h + 9 h^{2} + h^{3}

Solution steps

(3 + h)^{3}

Apply Perfect Cube Formula:

(a + b)^{3} = a^{3} + 3 a^{2} b + 3 a b^{2} + b^{3}

(3 + h)^{3} = 3^{3} + 3 \cdot 3^{2} h + 3 \cdot 3 h^{2} + h^{3}

= 3^{3} + 3 \cdot 3^{2} h + 3 \cdot 3 h^{2} + h^{3}

Simplify

3^{3} + 3 \cdot 3^{2} h + 3 \cdot 3 h^{2} + h^{3} : 27 + 27 h + 9 h^{2} + h^{3}

= 27 + 27 h + 9 h^{2} + h^{3}
