1.(3x+5y)⁴= 2.(3x-5y)⁴= TOLONG JAWAB PLISSSS.... TERIMAKASIH

1 ).
= ( 3x + 5y) (3x + 5y) (3x + 5y ) (3x + 5y )
catatan: (jgn dtlis cttnny cma ksi tw) 2 sja dlu yg dkrjakn krna hsilnya sma ( 3x + 5y) (3x + 5y)
^artinya pangkat
= 9x^2 + 15xy + 15xy + 25y^2
= 9x^2 + 30xy + 25y^2

= 9x^2 +30xy + 25y^2 + 9x^2 + 30xy + 25y^2
= 9x^2 + 9c^2 + 30xy + 30xy + 25y^2 + 25y^2
= 18x^2 + 60xy + 50y^2

2).
= (3x - 5y) (3x - 5y) (3x - 5y) (3x - 5y)
ctattn sma kyk diatas

= 9x^2 - 15y - 15y + 25 y^2
=9x^2 - 30y + 25y^2

= 9x^2 -30y + 25y^2 + 9x^2 - 30y+ 25y^2
=9x^2 +9x^2 -30y - 30y + 25y^2 + 25y^2
= 18x^2 -60y + 50y^2
