Question

Evaluate.
X =
-(-2)^(-2)2 -4(1)(-8)
2(1)

Answer 1

`x = (129)/(2)`

Explanation:

`x = ( - 2 {)}^( - 2) * 2 - 4 * 1 * ( - 8) * 2 * 1`

`x = ( - 2 {)}^( - 2) * 2 + 4 * 1 * 8 *2 * 1`

`x + 2( ( - 2 {)}^( - 2) + 4 * 8)`

`x = 2( {2}^( - 2) + 32)`

`x = 2( \frac{1}{ {2}^(2) } + 32)`

`x = 2( (1)/(4) + 32)`

`x = 2 * (129)/(4)`

`x = (129)/(2)`
