Question

Calculaţi:
a) 67 + 75: 5;
b)92 - 6 × 13;
Calculați :
a) 10 × ( 3⁴:9+2⁰);
( 8 × 2⁴ - 2³ ) : 10
repede va rog!​

Answer 1

Răspuns:

75÷5=15 15+67=82

6*13=78 92-78=14

3 la put 4=81:9=9 2 la put 0=1 9+1=10 10*10=100

8*16=128-8=120 120÷10=12

Answer 2

67 + 75 : 5 = 67 + 15 = 82

92 - 6x13 = 92 - 78 = 14

10×(3⁴ : 9 + 2⁰) = 10×(3⁴ : 3² + 1) = 10×(3² + 1) = 10×(9 + 1) = 10×10 = 100

(8×2⁴ - 2³) : 10 =

= (2³×2⁴ - 2³) : 10

= 2³(2⁴ - 1) : 10

= 8(16 - 1) : 10

= 8×15 : 10

= 120 : 10

= 12
