Question

(2/3x во 2 степени z) во 2 степени

Answer 1

Объяснение:

$( \frac{2}{3} x {}^{2} z) {}^{2} = ( \frac{2}{3} x {}^{2} z {}^{1} ) {}^{2} = \left(\frac{2}{3}\right)^{2}\left(x^{2}\right)^{2}\left(z^{1}\right)^{2} =\frac{4}{9}\left(x^{2}\right)^{2}\left(z^{1}\right)^{2} =\frac{4}{9}x^{2\times 2}z^{2} =\frac{4}{9}x^{4}z^{2}$
