Penjelasan dengan langkah-langkah:
Materi : Matematika - Operasi Perpangkatan
Note :
[tex]\frac{xy}{y} = x\\\\\frac{-9}{3} = -3\\\\\frac{x^{2} }{x} =x^{2-1} =x[/tex]
[tex]\frac{d}{\frac{x}{y} } =\frac{d*y}{x}[/tex]
Jawaban :
Soal 1
[tex]12xy : 6y = \frac{12}{6} * \frac{xy}{y} = 2 * x = 2x[/tex]
Soal 2
[tex](-9ab) : 3b = \frac{-9}{3} *\frac{ab}{b} = -3*a = -3a[/tex]
Soal 3
[tex]a^{3} :a^{2} =a^{3-2} = a^{1}=a[/tex]
Soal 4
[tex]10x^{2} y:(-2xy)=(\frac{10}{-2} )*(\frac{x^{2}y}{xy} )= -5*x=-5x[/tex]
Soal 5
[tex](9x^{2} ):\frac{3}{5} x=(\frac{9}{\frac{3}{5}} )*(\frac{x^{2} }{x}) =(\frac{9*5}{3})*x=15x[/tex]
Soal 6
[tex]4ab:(-\frac{2}{3} b)=\frac{4}{-\frac{2}{3} } *\frac{ab}{b} =\frac{-4*3}{2} *a=-6a[/tex]
