tolong bantuin dong pke cara ( 1-5)

Answer 1

1)
a) (m³n + 8)(m³n -5)
= m^6n² + (8-5)m³n + (-5x8)
= n²m^6 + 3m³n -40

b) (3-c²d)(4-4c²d)
= (3x4) + (-4-12)c²d + (c²d)²
= 12 - 16c²d + c⁴d²

c) (0,1x + 0,4y)² = 0,01x² + 0,08xy + 0,16y²

2)
a) 6¹²/6^10 = 6^(12-10) = 6²
b) (-7)^8/(-7)³ = (-7)^(8-3) = (-7)^5
c) = (-3)⁴+³-² = (-3)^5
d) = 30/5 p^(8-7) x 4/4 q⁴-³
= 6pq

3) a²bc³ = 5³
ab² = 56
>>>≥>>>>>> x
a³b³c³ = 5³ x 56
(abc)³ = 7000
abc = ³√7000
abc = 10 ³√7

4) a) = 1/6³
b) = 1/9^5
c) = 1/b³a^7
d) = b⁴/a²

5)
a) = 870.000.000
b) = 2.100.000.000
c) = 1.230.000
d) = 97.600.000
