Ответы

Автор ответа: ivanshevchuk08

Ответ:

x = 5⁴.

Объяснение:

5⁵ * 5^(-2) / x = 5⁷

5⁵ * 5^(-2) = 5^(5 - 2) = 5³

5³ / x = 5⁷

5³ * x = 5⁷

x = 5⁷ / 5³

x = 5^(7 - 3) = 5⁴

x = 5⁴.

Үш мың жыл бұрын Қазақ даласында атақты арғы аталарымыз қуатты сақ тайпалары өмір сүрген. Гректер оларды «кентаврлар» (ежелгі грек аңызындағы ат басты адам) деп атап, оларды аңыз қылған. Көне грек тарихшысы Геродоттың айтуынша, әйгілі Геракл да сақ тайпасынан шыққан. Сақтардың жерін ешкім жаулап ала алмаған. Дұшпандар сақ әйелдерінен қатты қорқатын, өйткені олар ерлермен тең дәрежеде соғысқан. -
