Question

[( 9² - 2⁴ x 5 ) : 10 + 7¹³ : (7³)⁴] x 2²​

Answer 1

Răspuns:

Explicație pas cu pas:

[( 9² - 2⁴ x 5 ) : 10 + 7¹³ : (7³)⁴] x 2²​=

= [ ( 81 - 16 x 5 ) : 10 + 7¹³ : 7³ˣ⁴ ] x 4 =

= [ ( 81 - 80 ) : 10 + 7⁽¹³⁻¹²⁾ ] x 4 =

= ( 1/10 + 7 ) x 4 =

= ( 1/10 + 70/10 ) x 4 =

= (71/10 ) x 4 =

= ( 71 x 2 ) / 5 =

= 142/5 =

= 28 intregi si 2/5

Answer 2

[ ( 9 ^ 2 - 2 ^ 4 × 5 ) : 10 + 7 ^ 13 : ( 7 ^ 3 ) ^ 4 ] × 2 ^ 2 =

[ ( 81 - 16 × 5 ) : 10 + 7 ^ 13 : 7 ^ 12 ] × 4 =

[ ( 81 - 80 ) : 10 + 7 ^ 1 ] × 4 =

( 1 : 10 + 7 ) × 4 =

( 0, 1 + 7 ) × 4 =

7, 1 × 4 = 28, 4
