(lg5)^2-(lg2)^2+2lg√10/5+0.25^-1/2 X 1/64的立方根
(lg5)^2-(lg2)^2+2lg√10/5+0.25^-1/2 X 1/64的立方根

(lg5)^2-(lg2)^2+2lg√10/5+0.25^-1/2 X 1/64的立方根
(lg5)^2-(lg2)^2=lg2.5
2lg√10/5=lg0.4
(lg5)^2-(lg2)^2+2lg√10/5=lg1=0
(lg5)^2-(lg2)^2+2lg√10/5+0.25^-1/2 X 1/64=1/8
(lg5)^2-(lg2)^2+2lg√10/5+0.25^-1/2 X 1/64的立方根=1/2
