Question

при приведите к дроби со знаменателем 4а^5 с^2

Answer 1

$\frac{4a}{a^3c}=\frac{4a\cdot 4a^2c}{a^3c\cdot 4a^2c}=\frac{16a^3c}{4a^5c^2}\\\\\frac{5ac^3}{a^2c}=\frac{5ac^3\cdot 4a^3c}{a^2c\cdot 4a^3c}=\frac{20a^4c^4}{4a^5c^2}\\\\\frac{4a}{2ac^2}=\frac{4a\cdot 2a^4}{2ac^2\cdot 2a^4}=\frac{8a^5}{4a^5c^2}\\\\\frac{ac^4}{0,5a^2c}=\frac{ac^4\cdot 8a^3c}{0,5a^2c\cdot 8a^3c}=\frac{8a^4c^5}{4a^5c^2}\\\\\frac{5,5ac}{a^2c}=\frac{5,5ac\cdot 4a^3c}{a^2c\cdot 4a^3c}=\frac{22a^4c^2}{4a^5c^2}\\\\\frac{-ax}{a^3c}=\frac{-ax\cdot 4a^2c}{a^3c\cdot 4a^2c}=\frac{-4a^3cx}{4a^5c^2}$
