tlg no 1-5 pakai cara. terimakasih

1. a.) 19 x 11 - (1200:4) : 5 =n
=>209 - 300 : 5 =n
=>209 - 60 =n
n=149

b.) 650 : 26 + 13 x 19 -125 =n
=>25 + 247 - 125 =n
n=147

c.) 987 - 16 x 17 + 768 : 32 =n
=>987 - 272 + 24=n
=>n=739

2.(∛343 + ∛2197)/(∛125 - ∛27)
=>(7 + 13)/(5 - 3)
=>20/2 = 10

3.72=2 x 2 x 2 x 3 x 3
180=2 x 2 x 3 x 3 x 5
216= 2 x 2 x 2 x 3 x 3 x 3


FPB=2 x 2 x 3 x 3=36

5. V=9261 cm³
s=∛V
s=∛9261
s=21 cm

Maaf ya cuma bantu 4 nomor :)
