Answer 1

Răspuns:

Explicație pas cu pas:

[7^23 × (1+7^0+ 5^3 : 25) ]: 7^22 =

[7^23 × ( 1 + 1 + 5^3:5^2 ) ]:7^22 =

[7^23 × ( 1+1 + 5 ) ] : 7^22 =

[7^23 × ( 2+5) ] : 7^22 =

(7^23 × 7 ) : 7^22 =

7^24 : 7^22 =

7^24-22 =

7^2 =

49

Answer 2

[ 7 ^ 23 × ( 1 + 7 ^ 0 + 5 ^ 3 : 25 ) ] : 7 ^ 22 =

[ 7 ^ 23 × ( 1 + 1 + 125 : 25 ) ] : 7 ^ 22 =

[ 7 ^ 23 × ( 2 + 5 ) ] : 7 ^ 22 =

( 7 ^ 23 × 7 ) : 7 ^ 22 =

7 ^ 24 : 7 ^ 22 =

7 ^ ( 24 - 22 ) =

7 ^ 2 = 49
