Tolong di jawab semuanya sekarang juga

15) 51 = 3 × 17
68 = 2² × 17
85 = 5 × 17
fpb = 17 ( D )

16) 2.183 ÷ ( -59) - ( -37) + 167
= ( -37) + 37 + 167
= 167 ( B )

17) 19³ - 13³
= 6.859 - 2.197
= 4.662 ( A )

18) 60 = 2² × 3 × 5
72 = 2³ × 3²
90 = 2 × 3² × 5
fpb = 2 × 3 = 6
kpk = 2³ × 3² × 5 = 360
jumlah = 6 + 360 = 366 ( D)

19) angka gak jelas

20) Lp = 6 × s²
1.734 = 6 × s²
s² = 1.734 ÷ 6
s = √289
s = 17 dm
V = s³
V = 17 × 17 × 17
= 4.913 dm³
= 4.913 liter ( D )
