Jika a=3, b= -2 dan c=½, tentukan ab^ 5 c^-² dibagi a² b-² c³
Jawaban Terkonfirmasi
A b^(5) c^(-2) /{a^(2) b^(-2) c^(3)}
=a^(1-2) b^(5-(-2)) c^(-2-3)
=a^(-1) b^(7) c^(-5)
=b^(7) /{a c^(5)} = (-2)^(7) /{(3) (1/2)^5}
= -128 /{3/32} = -4096/3
Ab^5 c^-2 / a² b^-2 c^3
= a^-1 b^7 c^-5
= (-2)^7 / (3) (1/2)^5
= (-2)^7 * 2^5 / 3
