Question

A = ( - 5 ) × ( - 3 ) × 2 × 2² ÷ √ 4 e B= 10 × ( - 4 ) ÷ 8 + 8
Qual o valor de :
B - A + 5

Answer 1

Resposta:

B-A+5=52

a=60

b=3

A=15×2×4÷2

30×2

a=60

b=-40÷8+8

b=-5+8

b=3

B-A+5=

3-60+5

-60+8

-52

Answer 2

$A=(-5)*(-3)*2*2^2:\sqrt{4}$

$A=15*2*4:2$

$A=30*4:2$

$A=120:2$

$A=60$

$B= 10 * ( - 4 ) : 8 + 8$

$B=-40:8+8$

$B=-5+8$

$B=3$

Valor de:

$B - A + 5$

$3-60+5$

$-57+5$

$-52$
