Question

calcule as expressões

A)
$(3.25 + 2.75) \times (3.72 - 2.75)$
B)
$( {1.5)}^{2} + {(3.8)}^{0} \times (1.2 + 1.1)$
C)
$\frac{(2}{(3} + \frac{ {1)}^{2} }{2)}$
​

Answer 1

Resposta:

$3.25 + 2.75$

Answer 2

Olá, siga a explicação:

A)

$(3,25 + 2,75) \times (3,72 - 2,75) = (6) \times (0,97) = \boxed {5,82}$

B)

$(1,5)^2 + (3,8)^0 \times (1,2 + 1,1) = 2,25 + 1 \times 2,3 = 2,25 + 2,3 = \boxed {4,55}$

C)

$\left (\dfrac{2}{3} + \dfrac{1}{2} \right ) ^2 = \left ( \dfrac{7}{6} \right ) ^2 = \boxed { \dfrac{49}{36} }$
