Simplify the variable expression:
1. (13)(-x)
My answer: -13x
2. (-4)(-x)^3(x)(-1/8)
My answer: 1/2 • -3x
I'm not sure about number 2. Thanks
If your expresion mean :
( - 4 ) * ( - x ) ^ 3 * x * ( - 1 / 8 )
then :
( - 4 ) * ( - x ) ^ 3 * x * ( - 1 / 8 ) =
- 4 * ( - 1 / 8 ) * ( - x ^ 4 ) =
( 1 / 2 ) * ( - x ^ 4 ) =
- x ^ 4 / 2
