Question

(2/3)×(2/3)³×(2/3)⁴​

Answer 1

Ответ:

Объяснение:

Формулы:

$a^ma^n=a^{m+n}$

$\displaystyle \bigg( \frac{a}{b} \bigg)^n=\frac{a^n}{b^n}$

Решение:

$\displaystyle \bigg (\frac{2}{3} \bigg)*\bigg(\frac{2}{3} \bigg)^3*\bigg(\frac{2}{3} \bigg)^4=\bigg(\frac{2}{3} \bigg)^{1+3+4}=\bigg(\frac{2}{3}\bigg)^8=\frac{2^8}{3^8} =\frac{256}{6561}$
