(3x-4)²=64x²-10x+25=644（x-1）²-9=0

答：
(3x-4)²=64
(3x-4)²=8²
3x-4=8或者3x-4=-8
解得：x=4或者x=-4/3
x²-10x+25=64
(x-5)²=8²
x-5=-8或者x-5=8
解得：x=-3或者x=13
4(x-1)²-9=0
(x-1)²=9/4
(x-1)²=(3/2)²
x-1=3/2或者x-1=-3/2
解得：x=5/2或者x=-1/2

(3x-4)²=64
3x-4=±8
即：3x-4=8或3x-4=-8
∴x=4或x=-4/3
x²-10x+25=64
x²-10x-39=0
(x-13)(x+3)=0
x=13或x=-3
4（x-1）²-9=0
（x-1)²=9/4
x-1=±3/2
即：x-1=3/2或x-1=-3/2
∴x=5/2或x=-1/2
