8(a+2)的2次方+3| b-3 |+16(c+0.5)的2次方=0.求(a的b次方+2c)的2次方

问题描述:

8(a+2)的2次方+3| b-3 |+16(c+0.5)的2次方=0.求(a的b次方+2c)的2次方

a+2=0,b-3=0,c+0.5=0
a=-2,b=3,c=-0.5
(a^b+2c)^2=(-8-1)^2=81

8(a+2)的2次方+3| b-3 |+16(c+0.5)的2次方=0.

8(a+2)^2=0.
a=-2

3| b-3 |=0
b=3
16(c+0.5)^2=0.
c=-0.5
(a^b+2c)^2
=[(-2)^3+2*(-0.5)]^2
=(-8-1)^2
=(-9)^2
=81
