Question

[7la puterea 23×(1+7la puterea0 +5la puterea 3 ÷25 )]÷7la puterea 22

Answer 1

[7^23 * (1+1+5^3 : 5^2)]: 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

Explicație pas cu pas:

[ 7²³ · ( 1 + 7⁰ + 5³ : 25 ) ] : 7²² =

= [ 7²³ · ( 1 + 1 + 125 : 25 ) ] : 7²²

= [ 7²³ · ( 1 + 1 + 5 ) ] : 7²²

= [ 7²³ · 7 ] : 7²²

= 7²³⁺¹ : 7²²

= 7²⁴ : 7²²

= 7²⁴⁻²²

= 7²

= 49
