1、=2√2+√2/4=9√2/4
2、=-8√7+√7/7=-55√7/7
2√2+1/2*√(1/2)-8√7+√(1/7)
=2√2+1/2*√2 /2-8√7+√7/7
=2√2+√2 /4-(8-1/7)√7
=(2+1/4)√2-(55/7)√7
=9√2/4-55√7/7 (4分之9倍根号2-7分之55倍根号7)

5倍根号2-9倍根号1/3+1/2倍根号48等于多少
5倍根号1/5+1/2倍根号20-5/4倍根号4/5
1/2倍根号10*(3倍根号15-5倍根号6)
计算:2倍根号12+3倍根号48-3倍根号1/3
1/(2倍根号1+根号2)+1/(3倍根号2+2倍根号3)+1/(4倍根号3+3倍根号4)+···+1/(100倍根号99+99倍根号10
根号(3-2倍的根号2)=根号(2-2倍的根号2+1)
