Answer 1

Explicație pas cu pas:

a) √ 972 - 3 × 24 + √ 1255 - 11 × 21

= √ 972 - 72 + √ 1255 - 231

= √ 900 + 1024

= 30 + 32

= 62

b) √ 3258 + 18 × 19 + √ 5000 + 40 × 35

= √ 3258 + 382 + √ 5000 + 1400

= √ 3600 + √ 6400

= 60 + 80

= 140

c) √ 6525 - 15 × 60 - √ 905 - 20 × 14

= √ 6525 - 900 - √ 905 -280

= √ 5625 - √ 625

= 75 - 25

= 50

d) √ 673 - 12 × 32 + √ 871 + 11 × 18

= √ 673 - 384 + √ 871 + 198

= √ 289 + √ 1089

= 17 + 33

= 50
