Verified answer

a^(n + m) = a^n * a^n

a^ log(a) b = b

5^(3 + log(5) 15) = 5^3 * 5^log(5) 15 = 125 * 15 =  1875

Verified answer

Ответ:

1875

5^(3 + log₅15) = 5³ * 5^(log₅15) = 125 * 15 = 1875

Объяснение:

5^(3 + log₅15) = 5³ * 5^(log₅15) по формуле a^(b + c) = a^b + a^c

5^(log₅15) = 15 по формуле a^(logₙb) = b
