simplify (-5x)^2

Solution

simplify

(- 5 x)^{2}

Solution

25 x^{2}

Solution steps

(- 5 x)^{2}

Apply exponent rule:

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

if

n

is even

(- 5 x)^{2} = (5 x)^{2}

= (5 x)^{2}

Apply exponent rule:

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

(5 x)^{2} = 5^{2} x^{2}

= 5^{2} x^{2}

5^{2} = 25

= 25 x^{2}
