Question

Помогите СРОЧНО 1.2.11, 1.2.12

Answer 1

$5^2*25*5^2=5^2*5^2*5^2=5^6$
$5^7:5^3*125=5^7:5^3*5^3=5^7$
$( frac{1}{3}) ^3*( frac{1}{3})^5* frac{1}{27} = ( frac{1}{3}) ^3*( frac{1}{3})^5*( frac{1}{3})^3=( frac{1}{3})^{11}$
$( frac{1}{3})^3 * (frac{1}{3})^2 * frac{1}{81} = (frac{1}{3})^3*(frac{1}{3})^2*(frac{1}{3})^4=(frac{1}{3})^{9}$
