Answer 1

Răspuns:

5²⁶+5²⁵-15²⁴:3²⁴ = 5²⁵(5+1) -3²⁴·5²⁴:3²⁴=6·5²⁵-5²⁴·(3²⁴:3²⁴)=

6·5²⁵-1·5²⁴ =5²⁴·(6 - 1) =5²⁴·5 = 5²⁵ (F)

______________

7·42²³-9·4²²=4²²(7·4-9)=4²²(28-9)=4²²·19 (A)

__________

49¹¹:7¹¹+7¹³:7 =(7²)¹¹:7¹¹+7¹²=7²²:7¹¹1+7¹² =

7¹¹+7¹²=7¹¹·(1 + 7) =7¹¹·8 (A)

______________

3·6²⁰⁰⁸-2²⁰⁰⁷·3²⁰⁰⁷- 5·6²⁰⁰⁶= 3·6²⁰⁰⁸-(2·3 )²⁰¹⁷-5·2²⁰⁰⁶= 6²⁰⁰⁶·(3·6²-6-5 ) =

6²⁰⁰⁶·(3·36 -6-5 )= 6²⁰⁰⁶·(108-6-5 )= 6²⁰⁰⁶·97 (A)
