Question

Resolva as expressões abaixo:

a) √16 + √36 =

b) √25 + √9 =

c) √49 - √4 =

d) √36 - √1 =

e) √9 + √100 =

f) √4 x √9 =

Answer 1

$a) \sqrt{16} + \sqrt{36} = 4 + 6 = 10 \\ \\ b) \sqrt{25} + \sqrt{9} = 5 + 3 = 8 \\ \\c) \sqrt{49} - \sqrt{4} = 7 - 2 = 5 \\ \\ d) \sqrt{36} - \sqrt{1} = 6 - 1 = 5 \\ \\ e) \sqrt{9} + \sqrt{100} = 3 + 10 = 13 \\ \\ f) \sqrt{4} \times \sqrt{9} = 2 \times 3 = 6$

Answer 2

a) √16 + √36

4 + 6 = > 10

===

b) √25 + √9

5 + 3 => 8

===

c) √49 - √4

7 - 2 => 5

===

d) √36 - √1

6 - 1 => 5

===

e) √9 + √100

3 + 10 => 13

===

f) √4 x √9

2 . 3 => 6
