A) x:8x b) 120p² : 3p² c) 625 xy : 25 xy d) 35(x²+y²) : 7(x²+y²)

A) x : 8x = 8
Caranya
=> x : x = x¹⁻¹ = habis/tidak ditulis
=> 8

b) 120p² : 3p² = 40
Caranya
=> 120 : 3 = 40
=> p² : p² = p²⁻² = habis/tidak ditulis

c) 625xy : 25xy = 25
Caranya
=> 625 : 25 = 25
=> xy : xy = xy¹⁻¹ = habis/tidak ditulis

d) 35 (x² + y²) : 7 (x² + y²) = 10
Caranya
=> (35 × x²) (35 × y²) : (7 × x²) (7 × y²)
=> 35x² + 35y² : 7x² + 7y²
=> (35x² : 7x²) (35y² : 7y²)
=> (35 : 7 = 5) (x² : x² = x²⁻² = habis)
>>(35 : 7 = 5) (y² : y² = y²⁻² = habis)
=> 5 + 5
=> 10
