Question

Tolong dibantu yaaa,, pleaseeee!! butuh bgt dikumpulin hari ini,, yang dibuletin tolong di jawab ya,, makasih

Answer 1

3.a) 15ab = 3.5.ab
20 ab = 2².5.ab
KPK = 2².3.5.ab = 60ab


b) 10a²b^3c = 2.5.a²b^3c
15b²c²d = 3.5.b²c²d
KPK = 2.3.5.a²b^3c²d = 30a²b^3c²d


c) 24p²q = 2^3.3.p²q
36p^3q² = 2².3².p^3q²
60 pqr = 2².3.5.pqr
KPK = 2^3.3².5.p^3q²r = 360p^3q²r


d) 16pq²r = 2^4.pq²r
30qr²s² = 2.3.5.qr²s²
36p^3r²s^5 = 2².3².p^3r²s^5
KPK = 2^4.3².5.p^3q²r²s^5 = 720p^3q²r²s^5




4.a) 2x = 2.x
-3x² = -3.x²
FPB = x


b) 4x²y = 2².x²y
12xy² = 2².3.xy²
FPB = 2².xy = 4xy


c) 48a^3b^5 = 2^4.3.a^3b^5
52a²b^3c² = 2².13.a²b^3c²
FPB = 2².a²b^3 = 4a²b^3


d) 12pq = 2².3.pq
6q²r = 2.3.q²r
15p²qr = 3.5.p²qr
FPB = 3q
