Question

помогите решить
$( - 3 \sqrt{2})^{2}$
$\frac{ \sqrt{x5} \times \sqrt{x} }{x}$
​

Answer 1

$(-3\sqrt2)^2=(-3)^2\cdot (\sqrt2)^2=9\cdot 2=18\\\\\\\frac{\sqrt{x^5}\cdot \sqrt{x}}{x}=\frac{x^{\frac{5}{2}+\frac{1}{2}}}{x}=\frac{x^3}{x}=x^2$

Answer 2

Объяснение:

(-3√2)² = (-3)² × √2 = 9 × 2 = 18

(√х^5 × √х)/(х) = (√х^5 × х)/(х) = (√х^6)/(х) = (х³)/(х) = х²
