计算;根号529-根号22右9/16+(-根号4.41)根号169-根号1-16/25乘以根号1右9/16

计算;根号529-根号22右9/16+(-根号4.41)根号169-根号1-16/25乘以根号1右9/16
计算;根号529-根号22右9/16+(-根号4.41)
根号169-根号1-16/25乘以根号1右9/16

计算;根号529-根号22右9/16+(-根号4.41)根号169-根号1-16/25乘以根号1右9/16
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)
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
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
