Question

rút gọn phân số;

a,\(\frac{25^4}{5^6.3^2}\)

b, \(\frac{3^8.6^8}{18^8}\)

c, \(\frac{(x^3.y)^4}{x^4.y^3}\)

d, \(\frac{-x^6}{x^2}\)

e, \(\frac{(-x)^6}{x^2}\)

Answer 1

\(a,\frac{25^4}{5^6.3^2}=\frac{5^8}{5^6.3^2}=\frac{5^2}{3^2}\)

Answer 2

\(d,\frac{-x^6}{x^2}=-x^4\)

e làm giống hết bài d

Answer 3

b, \(\frac{3^8.6^8}{18^8}\)

\(=\frac{3^8}{3^8}\)

\(=1\)

Answer 4

c, \(\frac{\left(x^3.y\right)^4}{x^4.y^3}\)

\(=\frac{x^{12}.y^4}{x^4.y^3}\)

\(=x^3y\)
