((16x⁻¹y²z ⁻²)/(12x⁻⁵y⁻¹))⁻¹.((6x²yz⁻¹)/(4x⁻⁵z⁻³))²

Jawaban yang benar adalah 72x⁶y²z³.

Pada bilangan berpangkat negatif berlaku
1/m^(-1) = m
a^(m)/a^(n) = a^(m-n)
(a^(m))^(n) = a^(m.n)
a^(m).a^(n) = a^(m+n)

Pada operasi hitung bilangan bulat berlaku
-a + (-b) = -(a+b)
a-(-b) = a+b

((16x⁻¹y²z ⁻²)/(12x⁻⁵y⁻¹))⁻¹.((6x²yz⁻¹)/(4x⁻⁵z⁻³))²
=((16x⁻¹y²z ⁻²)/(12^(-1)x^(-5.-1)y^(-1.-1)).((6x²yz⁻¹)/(4²x^(-5.2)z^(-3.2))
= ((16x⁻¹y²z ⁻²)/(12^(-1)x^(5)y)) . ((6x².y.z⁻¹) / (16x^(-10).z^(-6)))
= ((16x^(-1-5).y^(2-1).z ⁻²) / (12^(-1))). ((6x^(2-(-10)).y.z^(-1-(-6)) / 16)
= (16 x^(-6).y.z ⁻²/(12)^(-1)) . (6x^(12).y.z^(5)/16)
= (x^(-6).y.z ⁻²/(12)^(-1)) . (6x^(12).y.z^(5))
= (12x^(-6).y.z ⁻²). (6x^(12).y.z^(5))
= 72x^(-6+12).y^(1+1).z^(-2+5)
= 72x⁶y²z³

Jadi hasil dari ((16x⁻¹y²z ⁻²)/(12x⁻⁵y⁻¹))⁻¹.((6x²yz⁻¹)/(4x⁻⁵z⁻³))² adalah 72x⁶y²z³.
