Question

RESUELVE LAS SIGUIENTES OPERACIONES
3^2X(15+5^2)+2^3X(15-5^2)X4
5X(4-2^2)+1X(8-5^2)

Answer 1

1)
3^2 X (15 + 25) + 2^3 X (15 - 25) X 4 => 9 X (40) + 8 X (-10) X 4 => 360 -120 = 240 
2)
5 X (4-4) + 1X(8-25) => 5X0 - 17 => 0-17= -17

Answer 2

a) 3² . (15 + 5²) + 2³ . (15 - 5²) . 4 = 
3² . (15 + 25) + 8 . (15 - 25) . 4 = 
3² . 40 + 8 . (-10) . 4 =
9 . 40 + 8 .(-10) . 4 =
360 + (-80) . 4 =
360 + (-320) = 
40 

b) 5 . (4 -2²) + 1 . (8 -5²)=
5 . (4 - 4) + 1 . (8 - 25) =
5 . 0 + 1 . (-17) = 
0 + (-17) =
-17
