simplify (-3x)^2

Solution

simplify

(- 3 x)^{2}

Solution

9 x^{2}

Solution steps

(- 3 x)^{2}

Apply exponent rule:

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

if

n

is even

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

= (3 x)^{2}

Apply exponent rule:

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

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

= 3^{2} x^{2}

3^{2} = 9

= 9 x^{2}
