计算:(根号24+根号二分之一)-(根号八分之一-根号6)一定要全过程
问题描述:
计算:(根号24+根号二分之一)-(根号八分之一-根号6)
一定要全过程
答
[√24+√(1/2)]-[√(1/8)-√6]
=[√(2²x6+√(1/2²x2)]-[√(1/4²x2)-√6]
=(2√6+1/2√2)-(1/4√2-√6)
=2√6+1/2√2-1/4√2+√6
=3√6+1/4√2
答
(√24+√1/2)-(√1/8-√6)
=(2√6+2√1/8)-(√1/8-√6)
=3√6+1/2√1/2
=3√6+1/4√2
答
原式=根号24+根号1/2-1/2乘根号1/2+根号6
=3乘根号6+1/2乘根号1/2
=3乘根号6+四分之根号2
答
(根号24+根号二分之一)-(根号八分之一-根号6)
=2倍根号6+2分之根号2-4分之根号2+根号6
=3倍根号6+4分之根号2
答
:(根号24+根号二分之一)-(根号八分之一-根号6)
=(2√6+0.5√2)-(0.25√2-√6)
=2√6+0.5√2-0.25√2+√6
=3√6+0.25√2
