expand (-2a^3)^2

Solution

expand

(- 2 a^{3})^{2}

Solution

4 a^{6}

Solution steps

(- 2 a^{3})^{2}

Apply exponent rule:

(- a)^{n} = a^{n},

if

n

is even

(- 2 a^{3})^{2} = (2 a^{3})^{2}

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

Apply exponent rule:

(a \cdot b)^{n} = a^{n} b^{n}

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

(a^{3})^{2} : a^{6}

= 2^{2} a^{6}

2^{2} = 4

= 4 a^{6}
