计算下列各式.(题目较多,当时请加,需参考答案.)
2个回答

(1)|根号3-2|+|根号3-1|-根号4

=2-根号3+根号3-1-2

=-1

(2)根号1-1又1/2×根号0-2/3×根号2又1/4

=1-0-2/3×根号9/4

=1-2/3×3/2

=1-1

=0

(3)三次根号-64-根号81-三次根号-27-三次根号-==-4-9-(-3)-(-1)

=-13+3+1

=-9

(4)根号2(2+根号2)-3根号3-2根号2+5根号3

=2根号2+2-3根号3-2根号2+5根号3

=2+2根号3

(5)根号7(根号7+1/根号7)-|根号7-2|

=根号7*根号7+根号7*1/根号7-(根号7-2)

=7+1-根号7+2

==10-根号7
