1) 25% от числа x,если x=(1/2)^4*4^3*3^4 2)х=3^3*2^4*(1/6)^2 3)x=(5/6)^2*24*(4/5)^2 Я...

1.
$x = ( \frac{1}{2} ) {}^{4} \times 4 {}^{3} \times 3 {}^{4}$
$x = 324$
$\frac{324}{x} = \frac{100}{25}$
$x = \frac{324 \times 25}{100}$
$x = 81$
2.
$x = 3 {}^{3} \times 2 {}^{4} \times ( \frac{1}{6} ) {}^{2}$
$x = 12$
$\frac{12}{x} = \frac{100}{25}$
$x = \frac{12 \times 25}{100}$
$x = 3$
3.
$x = ( \frac{5}{6} ) {}^{2} \times 24 \times ( \frac{4}{5} ) {}^{2}$
$x = \frac{32}{3} = 10 \times \frac{2}{3}$
$\frac{10 \times \frac{2}{3} }{x} = \frac{100}{25}$
$x = \frac{10 \times \frac{2}{3} \times 25 }{100}$
$x = \frac{8}{3} = 2 \times \frac{2}{3}$
