[tex]\frac{P_{2} }{P_{1} } =k^{2}[/tex]
[tex]\frac{a_{2} }{a_{1} } =k |*a_{1}[/tex] [tex]\frac{b_{2} }{b_{1} } =k|*b_{1}[/tex]
[tex]a_{2} =k*a_{1}[/tex] [tex]b_{2}=k*b_{1}[/tex]
[tex]P_{1} =a_{1}*b_{1}[/tex]
[tex]P_{2} =a_{2}*b_{2} \\[/tex]
[tex]P_{2}=k*a_{1} *k*b_{1}[/tex]
[tex]P_{2} =k^{2} *a_{1}*b_{1}[/tex]
[tex]\frac{P_{2} }{P_{1} } =\frac{k^{2}*a_{1}*b_{1} }{a_{1}*b_{1} } =k^{2}[/tex] [tex]\frac{P_{2} }{P_{1} } =k^{2}[/tex]
Mam nadzieję, że pomogłam <33
