Question

Determine o valor das expressões:
√49 + 4² =

10³ - √64 = ___________________________________________________________________________
√25 + √100 = _________________________________________________________________________
√81 - √9 =_____________________________________________________________________________
√36 + √225 = __________________________________________________________________________
√4 . √9 = _____________________________________________________________________________
√100 : √4 = ________________________________________________________________________
72 + 2³ + √16 =________________________________________________________________________

Answer 1

√49 + 4² = 7 + 16 = 23

10³ - √64 = 1000 - 8 = 992

√25 + √100 = 5 + 10 = 15

√81 - √9 = 9 - 3 = 6

√36 + √225 = 6 + 15 = 21

√4 . √9 = 2 . 3 = 6

√100 : √4 = 10 : 2 = 5

72 + 2³ + √16 = 72 + 8 + 4 = 84
