simplify (-2sqrt(2))^2

Solution

simplify

(- 22)^{2}

Solution

8

Solution steps

(- 22)^{2}

Apply exponent rule:

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

if

n

is even

(- 22)^{2} = (22)^{2}

= (22)^{2}

Apply exponent rule:

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

(22)^{2} = 2^{2} (2)^{2}

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

2^{2} = 4

= 4 (2)^{2}

(2)^{2} = 2

= 4 \cdot 2

Multiply the numbers:

4 \cdot 2 = 8

= 8
