Answer 1

Resposta:

a) 3×√25= 3×5-------> 15

b) 6×√9=6×3-----------> 18

c) 10×√36-30=10×6-30------> 30

d) 160+√64= 160+8----> 168

e)2×√81+90=2×9+90----> 108

f)√100:√25= 10:5----------> 2

g) 3×√49:7 3×7:7----------------> 3

h)9×√36:32= 9×6:32--------> 1.6 (aproximadamente)

i)7×√16:2+6=7×4:2+6------------> 20

Espero ter ajudado!!!! ;)
