expand (-sqrt(x))^2

Solution

expand

(- x)^{2}

Solution

x

Solution steps

(- x)^{2}

Apply exponent rule:

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

if

n

is even

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

= (x)^{2}

Apply radical rule:

a = a^{\frac{1}{2}}

= (x^{\frac{1}{2}})^{2}

Apply exponent rule:

(a^{b})^{c} = a^{b c}

= x^{\frac{1}{2} \cdot 2}

\frac{1}{2} \cdot 2 = 1

= x
