计算√0.49-³√8分之7-1-√(-3)²,|√5-3|+√(-2)²+(√5-1)º-√36,(x-5)³=-125
计算√0.49-³√8分之7-1-√(-3)²,
|√5-3|+√(-2)²+(√5-1)º-√36,(x-5)³=-125
计算√0.49-³√8分之7-1-√(-3)²,|√5-3|+√(-2)²+(√5-1)º-√36,(x-5)³=-125
√0.49-³√8分之7-1-√(-3)²
=0.7-³√(-1/8)-3
=0.7+1/2-3
=7/10+1/2-3
=7/10+5/10-30/10
=-18/10
=-9/5
|√5-3|+√(-2)²+(√5-1)º-√36
=3-√5+2+1-6
=-√5
(x-5)³=-125
(x-5)^3=(-5)^3
x-5=-5
x=0
√0.49-³√8分之7-1-√(-3)²=0.7-(-1/2)-3=-1.2
|√5-3|+√(-2)²+(√5-1)º-√36=3-√5+2+1-6=-√5
(x-5)³=-125
x-5=-5
x=0
好:
√0.49-³√8分之7-1-√(-3)²
=0.7-(-1/2)-3
=0.7+0.5-3
=-1.2
|√5-3|+√(-2)²+(√5-1)º-√36
=3-√5+2+1-6
=-√5
(x-5)³=-...
