simplify (-2t)^2

Solution

simplify

(- 2 t)^{2}

Solution

4 t^{2}

Solution steps

(- 2 t)^{2}

Apply exponent rule:

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

if

n

is even

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

= (2 t)^{2}

Apply exponent rule:

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

(2 t)^{2} = 2^{2} t^{2}

= 2^{2} t^{2}

2^{2} = 4

= 4 t^{2}
