计算;根号529-根号22右9/16+(-根号4.41)

根号529-根号22右9/16+(-根号4.41)
=23-19/4-2.1
=16.15

根号169-根号1-16/25乘以根号1右9/16
=13-1-16/25*5/4
=11.2

根号169=43
根号1-16/25=根号9/25=3/5
根号1右9/16=根号25/16=5/4
所以
=13-3/5*5/4
=13-3/4
=12又1/4

根号529-根号22右9/16+(-根号4.41)
解：根号529＝23
根号22右9/16＝19/4
根号4.41＝2.1
原式＝23-19/4+（-2.1）
＝16.15

根号169-根号1-16/25乘以根号1右9/16
解：根号169＝13
根号1-16/25＝3/5
根号1右9/16＝5/4
原式＝13-3/5×5/4
＝12.25
