Question

2(8ala 2-15)+(27÷3+4)2exponente
8(17-14)÷6-(12÷3-4)3exponente
(10÷4)2exponente

Answer 1

a)  2(8² - 15) + (27 /3 + 4 )² = 
2 (64 - 15) + (9 + 4)² =
2(49) + (5)² =
98 + 25 = 123

b)  8(17 - 14) / 6  - (12/3 -4)³ =
      8 (3)/6 - (4 -  4)³ =
       8 * 1/2 - (0)³ =
        4 - 0 = 4
c)  (10/4)² = 
      (5/2)² =
     25/4 = 6,25
