Solution

simplify

(- 3)^{2}

Solution

- 3

Solution steps

(- 3)^{2}

Apply rule:

(- a) = - a

(- 3) = - 3

= (- 3)^{2}

- 3 = 3 i

= (3 i)^{2}

Apply exponent rule:

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

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

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

(3)^{2} = 3

= 3 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= 3 (- 1)

Multiply the numbers:

3 (- 1) = - 3

= - 3
