ubahlah bentuk berikut ke pangkat positif
EKsponen
[tex]\sf x^m .x^n = x^{mn}[/tex]
[tex]\sf x^{-m} = \frac{1}{x^m}[/tex]
Penjelasan dengan langkah-langkah:
1.
[tex]\sf \dfrac{x^{-1}- xy^{-1}}{x^{-1} + y^{-1}}=[/tex]
[tex]\sf kalikan\ \frac{xy}{xy}[/tex]
[tex]\sf = \left( \dfrac{x^{-1}- xy^{-1}}{x^{-1} + y^{-1}}\right)\left(\dfrac{xy}{xy}\right)[/tex]
[tex]\sf = \dfrac{y- x^2}{y+ x}[/tex]
2.
[tex]\sf \dfrac{x^{-1}y- xy^{-1}}{x^{-1} y^{-1}}=[/tex]
[tex]\sf kalikan\ \frac{xy}{xy}[/tex]
[tex]\sf = \left(\dfrac{x^{-1}y- xy^{-1}}{x^{-1} y^{-1}}\right)\left (\dfrac{xy}{xy}\right)[/tex]
[tex]\sf = \dfrac{y^2- x^2}{1}= y^2- x^2[/tex]
