Question

calcule

a) 12+√36+23°

b)10-√49+3²

c) 12+√144

d) 80-√81​​

Answer 1

Resposta:

a) 19

b) 12

c) 24

d) 71

Explicação passo-a-passo:

A)

$12 + \sqrt{36} + 23^{0} \\\\= 12 + 6 + 1\\\\= 19$

B)

$10 - \sqrt{49} + 3^{2} \\\\= 10 - 7 + 9\\\\= 12$

C)

$12 + \sqrt{144} \\\\= 12 + 12\\\\= 24$

D)

$80 - \sqrt{81} \\\\= 80 - 9\\\\= 71$

Answer 2

) 19

b) 12

c) 24

d) 71

Explicação passo-a-passo:

A)

{36} + 23^{0} \\\\= 12 + 6 + 1\\\\= 19 12+36+230=12+6+1=19

B)

10 - {49} + 3^{2} = 10 - 7 + 9 = 12 10−49+32=10−7+9=12

C)

12 + {144} = 12 + 12 = 24 12+144=12+12=24

D)

80 - {81} = 80 - 9 = 71 80−81=80−9=71
