tolong bantu yaa Pr matematika aku yg ada diatas Plisss☺

1. (48x9)-432:12=432-432:12=0

2. 24=2x2x2x3
40 =2x2x2x5
fpb = 2x2x2=8
kpk = 2x2x2x3x5=120

3.
[tex] {42}^{3} = 74088 [/tex]
[tex] {48}^{2} = 2308[/tex]
jadi 74088-2308=71784

4.
[tex] \sqrt{144} + \sqrt{256} + \sqrt{121} = 12 + 16 + 11 = 39[/tex]

5. -5-(-23)+74=-5+23+74=92
