计算1.(π-3)的0次幂+根号8-|1-2倍根号2| 计算2.(-2)的3次幂×根号下121/4+根号64的立方根×(-1/2)的平方+(-1)2010次幂-根号27的立方根
问题描述:
计算1.(π-3)的0次幂+根号8-|1-2倍根号2| 计算2.(-2)的3次幂×根号下121/4+根号64的立方根×(-1/2)的平方+(-1)2010次幂-根号27的立方根
答
原式=0+2根号2-(2根号2-1) =0+1=1
答
(- 3)-² + √8 - 丨1 - 2√2丨- (√6 - 3)^ 0
= 3 -² + √(2 × 4)- (2√2 - 1)- 1
= 1 / 3 ² + 2√2 - 2√2 + 1 - 1
= 1 / 9 + 0 + 0
= 1 / 9
答
(π-3)的0次幂+根号8-|1-2倍根号2|
=1+2√2-(2√2-1)
=1+2√2-2√2+1
=2
2.(-2)的3次幂×根号下121/4+根号64的立方根×(-1/2)的平方+(-1)2010次幂-根号27的立方根
=-8×11/2+4×1/4+1-3
=-44+1+1-3
=-45
答
计算1.(π-3)的0次幂+根号8-|1-2倍根号2|
=1+2√2+1-2√2
=2
计算2.(-2)的3次幂×根号下121/4+根号64的立方根×(-1/2)的平方+(-1)2010次幂-根号27的立方根=-8x11/2+4x1/4+1-3
=-44+1-2
=-45
