√25+√36-√-64/27（x-1）²=25-（x-3）的三次方=27观察；因为（0.1）²=0.01,（0.01）²=0.0001,所以√0.01=0.1,√0.0001=0.01.若√x=a,则√0.01x=,你有什么发现?

Question

√25+√36
-√-64/27
（x-1）²=25
-（x-3）的三次方=27
观察；因为（0.1）²=0.01,（0.01）²=0.0001,所以√0.01=0.1,√0.0001=0.01.若√x=a,则√0.01x=____,你有什么发现?

Answer 1

√25+√36
=5+6
=11
-√-64/27
是不是立方根?
=-(-4/3)
=4/3
（x-1）²=25
x-1=±5
x=-4,x=6
-（x-3）的三次方=27
(x-3)³=-27
x-3=-3
x=0
观察；因为（0.1）²=0.01,（0.01）²=0.0001,所以√0.01=0.1,√0.0001=0.01.若√x=a,则√0.01x=__0.1a__,你有什么发现?
发现是：√0.01x=0.1√x
