tolongg buat post test matrikulasiii

Bab Eksponensial
Matematika SMA Kelas IX

1] p + q = 3
p = 3 - q
p . q = 2
(3 - q) . q = 2
3q - q² = 2
q² - 3q + 2 = 0
(q - 2) (q - 1) = 0
q = 2 → p = 3 - 2 = 1
atau
q = 1 → p = 3 - 1 = 2

p⁴ . q⁵ . p⁵ . q⁴
= p⁴⁺⁵ . q⁵⁺⁴
= p⁵ . q⁵
= 2⁵ . 1⁵
= 32
atau
= 1⁵ . 2⁵
= 32

2] 3² x 3⁴ x 3³
= 3²⁺⁴⁺³
= 3⁹
= 3³ˣ³
= (3³)³
= 27³

jawabannya C

3] (5² x 5³)⁴
= (5²⁺³)⁴
= (5⁵)⁴
= 5⁵ˣ⁴
= 5²⁰
= 5²ˣ¹⁰
= (5²)¹⁰
= 25¹⁰

jawabannya A
