If AB is opposite to each other, AC is reciprocal to each other, and the power of x = 4, find the power of - 3A + ac-3b + (A / b) of X to the power of 2014

If AB is opposite to each other, AC is reciprocal to each other, and the power of x = 4, find the power of - 3A + ac-3b + (A / b) of X to the power of 2014

5.5 is wrong
From the meaning of the title:
A + B = 0, that is, B of a = - 1
ac=1
X = 2 or - 2
When x = 2,
The power of X & # 178; - 3A + ac-3b + (B of a)
=The power of 4-3 (a + b) + 1 / 2 + (- 1)
=4-3 × 0 + 1 / 2
=3.5
When x = - 2,
The power of X & # 178; - 3A + ac-3b + (B of a)
=The power of 4-3 (a + b) - 1 / 2 + (- 1)
=4-3 × 0-1 / 2
=2.5
