Question

resolva as expressoes a) (-16) ; (+4) elevado a 2 + 14 b) raiz quadrada de 64 - 4 .(+5) + (-2) elevado a 3 = e)(1/3: 3/4) + (2/5 . 3/5\) f)4/5 + 3/10).2 g)4/5 + 3/10

Answer 1

Resposta:

Explicação passo-a-passo:

a) - 16 : 4² + 14

   - 16 : 16 + 14

       1 + 14 = 15

----------------------------

b) √64 - 4.(+ 5) + ( -2)³

      8 - 20 - 8 = - 20

---------------------------------------

e) ( 1/3 : 3/4) + ( 2/5.3/5)

     1/3.4/3 + 6/25

      4/9 + 6/25    mmc 9,25

     100/225   + 54/225 = 154/225

f) (4/5 + 3/10),2

   ( 8/10 + 3/10),2

         11/10. 2/1 = 22/10 = 11/5

g) 4/5 + 3/10

     8/10 + 3/10 = 11/10

bons estudos
