Question

\(A=\frac{a^2.a^7.b^2.c^8}{a^5.b^3.\left(-c\right)^4}\)

Answer 1

A = \(\frac{a^2.a^7.b^2.c^8}{a^5.b^3.\left(-c\right)^4}\)

   = \(\frac{a^9.b^2.c^8}{a^5.b^3.c^4}\)

   = \(\frac{a^4.c^4}{b}\)

Answer 2

\(A=\frac{a^2.a^7.b^2.c^8}{a^5.b^3.\left(-c\right)^4}=\frac{a^9.b^2.c^8}{a^5.b^3.c^4-1}=\frac{a^4.c^4}{b-1}=\frac{\left(a.c\right)^4}{b-1}\)

Chúc bạn học giỏi nha!

Answer 3

A = a^2.a^7.b^2.c^8/^5.b^3.(−c)^4 

   = a^9.b^2.c^8/a^5.b^3.c^4 

   = a^4.c^4/b 

Answer 4

A=a2.a7.b2.c8a5.b3.(−c)4 =a9.b2.c8a5.b3.c4−1 =a4.c4b−1 =(a.c)4b−1
