Question

выполните действия
A) (8x/a)^2*(ab/4x)^3
B)(9y/c^2)^2*(c/3y)^3
C)(2x^2/3y)^2:(4x^3/3y^2)^2

Answer 1

А)
$(frac{8x}{a})^2*( frac{ab}{4x})^3= frac{64a^3b^3x^2}{64a^2x^3}= frac{ab^3}{x}$
B)
$(frac{9y}{c^2})^2*( frac{c}{3y})^3= frac{81y^2c^3}{81c^4y^3}= frac{1}{cy}$
C) 
$(frac{2x^2}{3y})^2:( frac{4x^3}{3y^2})^2= frac{4x^4*9y^4} {9y^2*16x^6}= frac{y^2}{4x^2}=( frac{y}{2x})^2$
