Question

1) Calcule:
a) v25 + V16 =
c) V1 + V0 =
e) -V36 + V121 + 19 =
b) v9 - V49 =
d) v100-V81 + 14 =
f) 144 + V169 -V81 =​

Answer 1

Resposta:

Explicação passo-a-passo:

A) $\sqrt{25} + \sqrt{16} = 5 + 4 = 9$

B) $\sqrt{1} + \sqrt{0} = 1 + 0 = 1$

C)$- \sqrt{36} +\sqrt{121} + 19 = - 6 + 11 + 19 = 5 + 19 = 24$

D) $\sqrt{9} -\sqrt{49} = 3 - 7 = - 4$

E) $\sqrt{100} - \sqrt{81} + 14 = 10 - 9 + 14 = 1 + 14 = 15$

F) $144 + \sqrt{169} - \sqrt{81} = 144 + 13 - 9 = 157 - 9 = 148$

Answer 2

Resposta:

a)✓25+✓16

5+4=9

b)✓1+✓0

1+0=0

c)-✓36+✓121+19

- 6+11+19

5+19=24

d)✓9-✓49

3-7= -4

e) ✓100-✓81+14

10-9+14

1+14=15

f)144+✓169-✓81

144+13-9

157-9=148
