Answer 1

Respuesta:

(3*5+3)= 18 - (2*7+1) =15

18-15

=3

(3*5)+3(-2*7)+1

15+3-14+1

=5

3*(5+3)-2*(7+1)

3*8-2*8

24-16

=8

Answer 2

Respuesta:

a)  3 x (5 + 3) - (2 x 7) + 1 = 11

b) (3 x 5) + (3 - 2) x 7 +1 = 23

c)  3 x (5 + 3) - 2 x (7 + 1) = 8

d) (3 x 5) + 3 - (2 x 7) + 1 = 3

e) (3 x 5) + 3 - (2 x 7) + 1 = 5

f) 3 x (5 + 3 - 2) x (7 + 1) = 144

Explicación paso a paso:

a)  3 x (5 + 3) - (2 x 7) + 1 = 11        

3 x 8 -14 +1 = 23;     24 -14 +1 = 11;   10+1= 11

b) (3 x 5) + (3 - 2) x 7 +1 = 23

15+1 x 7 +1 = 23;   15 + 7 +1 = 23;   15 + 8 =23

c)  3 x (5 + 3) - 2 x (7 + 1) = 8

3 x 8 - 2 x 8= 8;   24-16 =8

d) (3 x 5) + 3 - (2 x 7) + 1 = 3

15+3-14+1= 3;  18-15=3

e) (3 x 5) + 3 - (2 x 7) + 1 = 5

15 +3 -14 +1 = 5;   18-14+1=5;  4+1=5

f) 3 x (5 + 3 - 2) x (7 + 1) = 144

3 x 6 x 8 = 144;   18 x 8 = 144
